Hello all This one the best python basic lecture you will ever get, In the entire video she never asked for subscribe or like. Let’s encourage her to do more courses like this and help crores of students and learner’s. Keep up the good work Shraddha and keep on helping people.
There's nothing wrong to ask from the viewers to subscribe to their channel as it can be someone's main source of income and without being so mean we can listen and do that thing so
@@neonblade209 I want to learn machine learning thats why I chose python so there is any way you can tell where I can learn DSA because leetcode and all other platforms doesnt start from basic It would be great help if you help me with this
The r+ does not always add the data at the beginning. its totally depends where the cursor is like if we use the read command and then write so in this case after reading data the cursor will be in the end and if then we use the write command then the new data will be added to the end of file: For example in this case: f = open("test.txt" , "r+") content = f.read() f.write("john" ) f.close() : now in this case "john" will be added to the end of file. so remember the cursor is not always in the beginning in r+ mode its totally depends what you have done before that line of code. Happy coding😊
00:01 Today we will cover Chapter Seven about file operations. 02:07 RAM is volatile memory and not suitable for permanent storage 06:02 Using physical files in day-to-day operations 08:25 Opening a file in read mode returns a text IO wrapper 13:18 Understanding file reading modes 15:23 Reading a file and printing its contents 19:13 Appending data to a file in A mode 21:17 Differences between different modes 25:09 Different file modes in Python: Read Plus, Write Plus, Append Plus 27:19 Using the 'with' syntax in Python automatically closes the file 31:48 We can delete any file by using the remove function in the os module. 34:24 Replace Java with Python in a file using the replace method. 38:59 Write a function to find the line number of the word 'learning' in a file. 41:02 The code checks if a word exists within a given data string and prints the line number if it does. 45:28 Extract individual numbers from a string and convert them to integers 47:20 The code splits a string of numbers separated by commas and prints them individually. Crafted by Merlin AI.
def replace("Java" , "python"): with open ("practice2.txt", "r" ) as f : date= f.read() n_data= data.replace("Java" , "python" ) print(n_data) with open("practice2.txt", "w"): f.write(n_data)
One thing to mention, that the 'in' operator in Python checks for a substring match, meaning it will return True even if only part of the word "learning" appears in the text. For example, if the text contains "lear" or any character that the word starts with, the code will still print the word is "found". At 41:37.
There is one thing Ma'am Shradha forgets to mention is that if anyone passes the path of a text file to the first parameter of the open function, so if you just copy and paste the path as it is in the double quotes, Python will give an error because in the path there are back slashes (\), and python treated back slashes as an escape sequence character. So to fix this, there are many options, but I find these two easy; either u can put r before the first double quote and so python will treat the path as a raw string or u can replace all single back slashes with double back slashes(\\) and so python will treat this as a normal back slash rather then treating it as a escape sequence character.
I wanted to point out that while the code used to import data from another file and count all the even numbers (without using the split function) was functioning, there is a serious bug. The issue is that you will never get the ending value because there is no comma to separate it. This can be fixed with a little tweak, but I thought it's good if I let everyone know.
