In the last program, the interpreter would give an error: "local variable 'a' referenced before assignment" To avoid this, before while loop, at line number 3, you'll have add one more line of code as follows: a =' ' and you're all good. :)
there is an error at 2:34 becoz we r opening a file(a) in write mode and trying to use read function in 4th line due to which print(p) will give an error
You don’t have to put delimiter keyword because the default delimiter is comma itself. Also, you don’t need a loop of .writerow(), you can just pass the nested list in .writerows()
7:40 sir f=open(............,'r') R=f.readlines() x=R[-1] print(x) se bhi toh ajayega as readlines list me bana dega and -1 backward indexing se usko print kradenge am i right?
above the loop take a= " "(space or empty string) when u write while a: (you mean to say while there is a character the loop will keep going and when u reach the end, there is no characters so the while condition becomes false and loop terminates.
@apni kaksha Bhaiya aapne reading of a binary file me exception handling jaise use of try & except blocks bataye nahi hai Bhaiya pls include this also🙏
10:52 Sir you have done a lot of errors while writing this code. The correct code is given below: c=open('lyrics.txt', 'r') a=True while a: a=c.readline() b=a.split() for i in b: if len(i)

the question 4 (9:51) I tried the code jo aapne bataaya tha but it showed error so mene khud se ek try kiya and its working completely fine.... def DISPLAYWORDS() : f= open("abc.txt",'r') a = f.read() l = a.split() for i in l: if len(i)
program at 7:37 doesn't work! it gives a runtime error as 'a is not defined', if you define initially a = f.readline(), after opening the file, it will still prints nothing This works for me: with open('test.txt', 'r') as f: a = f.readline() while a: b=a a = f.readline() print(b) And this also: with open('test.txt', 'r') as f: lastline = f.readlines()[-1] print(lastline)
