Error at 27:50 It should be:
print(f"{x} plus {y} is {x + y }" )

Great lecture! Always wondered about that “__name__” feature, explained so well

[mitchellsteindler]

I've been programming in python for a few months now, just teaching myself, and most of this lesson was very unfamiliar. For example import sys...I haven't seen that on any forum for any question I've searched.

[First_Principals]

It would be better to have scratch, C and python examples on the screen at the same time for easier comparison between the languages.

[nikhilchorge]

Which software is he working on. Is it possible to compare three languages on the same screen. Can anyone tell me ?

[tappr]

It's just too bad you're using get_string() which is a cs50 specific function rather than a native Python function.

[Patrick-xkhz]

So would the check function in python implemented at the end just use linear search?

[SourabhBhat]

The python code at 46:30 is not equivalent, as the function get_positive_int is not known to the interpreter. We may need to move that function up.

[amansinghbhadauria]

Everything in the lecture is very helpful but these cs50 libraries which are suppose to help us are unnecessary. Why don't we deal with the actual standards and not use these extra functions?

Thank You David for the lecture on Python

[vikashkumar-osmj]

[deeraj]

at 19:32, can we do, print("hello, f" + s)

[deeraj]

at 1:01:17 can we use variable name other than s?

[alimohmed]

if __name__ == '__main__' : simply mean .... execute everything in these file ...🤘❤💚

Hi Professor David I have completed the basics of Python and I have problems configuring programs. Do you recommend what to do after studying?

[enockkoech]

hello David what is wrong with this code?
Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> from math import sqrt
>>> def getLength ():
length = float(input("please enter length of triangle side"))
return length
side1 = getLenght()
SyntaxError: invalid syntax
>>>
