Having installed python 3.12, I have been able to test the if statements using handcalcs and there are numerous issues with using if statements within functions decorated with @handcalc(). 1) If your input value into the function is modified inside the function after the if statement, the rendering of that value will use the latest value instead of the value it was before the if statement. Here's an example: def func(x, y): if x < 20: y = x + 5 x = x + 6 return x, y In this example, if x = 10, 16 will be used in the rendering of all the lines, instead of using 10. The first rendered says y = x + 5 = 16 + 5 = 15 2) if the variable is just to be assigned a value then nothing will be rendered. Here's an example: def func(x): if x > 1: x = 1 return x In this example, the x = 1 will not be rendered. I hope these issues will be considered for fixing soon?

Hi, the conditional if statements do not work on python 3.13.1. They seem to work fine on 3.12. Is there any reason for this, and will it be possible to provide a fix soon?

Is it possible to place a symbol on the left hand side of an equation? For example when designing concrete d/h = 0.9

When I enter handcalcs.set_option() an error is returned saying set_options() missing 2 required positional arguments. How can I see the list of available options and what values they take if this does not work?

Not sure if you know but the conditional if statements do not work on handcalcs. I tried the same example in the documentation and it keeps saying that x is not defined even though it is defined in the previous cell.

@connorferster I have tried to add a symbol line to the MPa in the structural environment. However, it does not work. Furthermore, when I call forallpeople.environment(), the MPa is shown to equal 1.000Pa instead of 1N/mm^2. It seems that the library is linked to the unit case, in other words when I add a symbol of N/m^2 to the Pa unit, everything will follow this, so if something is in MPa it will be given MN/m^2 units. Is there no way to force the use of N/mm^2 when the definition of MPa is found in the calculations?

Is there any way to force the units of a calculation to be N/mm^2 instead of MPa? N/mm^2 is more common and expected in UK concrete design.

Very insightful. Where can we find more videos like this? I'm trying to think of a dissertation idea and some of this is helping me

Hi Connor I am using Quarto to render the equations in pdf. As some of the equations are quite long, the last part of the equations is missing in the pdf. Is there a way to wrap the equations within the page width. Thanks

Tried it in vscode + Juypter notebook. Cannot get exporting to html to work. Any ideas?

superb!!!!

Excellent, thank you.

Can SageMath be used?

Replaced mathcad, I can't afford its price. Thanks! I wanna mask some value when converting units, cz it will not give the final units I wanted. I am doing X=X.to("units") to convert the units, but it gives me an extra X=YY。Could you please tell me how to mask this extra line?

Awesome, thank you for the video

Hi Connor! Thank you for this resource. I noticed your latex outputs are aligned left, instead of aligned centered. What should I change in "set_option()" to align text left as you have it? handcalcs.set_option("math_environment_start", "aligned" ) handcalcs.set_option("math_environment_end", "aligned" )

Do more videos

Why he is not makin videos 😭😭

I am a student doing my final year project for tunnel analysis visualization and generating defects reports by editing python codes. I have always been so tired of doing manual calculations for my school work. I seriously need to learn programming to work more efficiently. Thanks a lot for inspiration.

How to align the rendered equations to left??

This is awesome! I have much work to do

handcalcs is sexy. gonna be useful for my engineering degree.

Thanks a lot Connor, i admire your work, this library its extremely useful, i've been working with it and i've found an issue i would like to ask you about: I've modified the structural environment trying to include some new units as kgf, kgf/m and kgf/m2 because, unfortunately, this units are commonly used in my daily calculations, my aproach has been this: "kgf": { "Dimension": [1,1,-2,0,0,0,0], "Factor": "0.10197", "Symbol": "kgf"}, "kgf_m": { "Dimension": [1,0,-2,0,0,0,0], "Factor": "0.101971", "Symbol": "kgf/m"}, "kgf_m2": { "Dimension": [1,-1,-2,0,0,0,0], "Factor": "0.1019716", "Symbol": "kgf/m²"}, However, i've found that sometimes the .to("kgf") or .to("kgf_m") or .to("kgf_m2") method works correctly, but sometimes it's stops working and returns to the default SI units (N, N/m, N/m2), i know i'm doing something wrong in the deffinition of the environment but i've been unable to solve it. Thanks in advance for your answer!!!

Thank you, Connor for creating this library for Python Jupyter users.

This is unbelievably powerful! Thank you so much! Is there a way of overwriting the units that are rendered? For example, I want 100 Pa shown as 0.1 kPa

I was not put in context. Not knowing where the files are you working on and so forth. But I am sure this is interesting for someone who know CTI file for example. For me was no clue where did you start.

Hi, nice content, is there any libraries of python that can help with details in dwg or IFC format? For example, draw a beam with reinforcement and export it to dwg. thanks

I haven't tried it yet but is there something special about the %%render magic that causes printing to html not to display input cells? Or does Jupyter turn off input cells anytime you print html?

Great! I do my technical report using dash. But I'm getting exited to use these libraries. Thanks!

hi, Unable to load: forallpeople.environment('structural') it says key error: 'Hz' for all people is installed.

hi connor, Great Video! Thanks. I am stuck in the last part where you export just the output [56]. My jupyterlab throws the error "No module named 'handcalcs.install_templates'" installed. can you please help with this, Thanks.

you are a true genius.

Hi Connor When I run the cell symbolic equations are not displayed. I only get the results (e.g. c=0.6). Is there something missing in the installation?

Hey guys🙂, I'm a first year civil engineering student. Could you please suggest me some key skills to lean in python. I can't like learn everything!

Thank Connor for works. I run import handcalcs.render but jupyter shows KeyError. what I am doing import handcalcs

Great video but I am getting Name error while inserting dimensions like L=10m, P=10KN/m**2 like names m , K M/**2 showing like are not defined. Please, assist me.

Wonderful library. It would be great if we could render one dimension vectors along with their units. I have been doing that in mathcad express using the range variable.

Hi Connor. I'm currently using handcalcs ver 1.6.5 I'm not well versed in LaTeX. What should I change in these global configurations to get rendered calculations to be left aligned? import handcalcs.render handcalcs.set_option("math_environment_start", "aligned") handcalcs.set_option("math_environment_end", "aligned")

Hi Connor. I see You use Bluebeam Revu. I wander if there is a way to automate certain boring and repeatable tasks in said programme (eg. updating titleblocks etc.)? Thanks!

Looks great but I can only get a render of the answer i.e. c = 0.6. The rest of the equations are not being generated? LAtex works ok using $ signs. Can you help?

Your video has inspired me to learn python/jupyter for my civil and structural engineering calculations. I have followed your video as best I can, but am having 2 issues: 1. The renders are not printing out the formula, always just the answer, for example S_x=b*d*2/6 just outputs Sx=133333.333m3 instead of the formula with variables, then the answer. %%render symbolic prints the formula, but no answer. Can anyone assist? 2. The greek symbol substitution doesn't seem to be working for me. I get a NameError: name 'alpha' is not defined. Can anyone assist?

Пошол устанавливать jupyterlab

Hello. Great module! Is it possible to render variables containing non-ASCII characters? Currently, if such a variable is used in an expression, only the name of the variable and the result are rendered, without an intermediate formula.

Hello Connor, is there a way we can use your library with pycharm for a desktop application?

Amazing . How can I show results in cm^2 instead of m^2 . I know the .prefix('c') . Nothing seems to show the results in cm^2 .... I finally got the answer

Can we legally use individual version of anaconda distribution on office computer? Or do we need to purchase a commercial licence?

Hi Connor, Thank for the handcalcs library. However, I get the message that module install_html is not defined. Can you please comment what could be the issue?
