How To Define Functions in Python 3

very helpful…keep up !!

In this line:

 name = str(input('Enter your name: '))

There is no need to call str() here, it’s already a string:

 name = input('Enter your name: ')
 print(type(name))

Output:

Enter your name: Sveta
<class 'str'>

Also, this for loop :

for x in range(0, 25):

doesn’t require 0 in range(0,25), you can just write it as range(25)

A tutorial on transforming Python3.6 into an executable .exe file would be great.

This is a great tutorial, but I still don’t quite understand what __name__ and '__main__' are used for. In the line

if __name__ == '__main__':
 main()

in more_names.py, what is the purpose of including if __name__ == '__main__':? Why wouldn’t we just plainly call the main() function as in hello.py?

Thank you so much. This helped me a lot!

Hello! I’m completely new with Python. I’m using PyCharm to edit and compile. My problem is that I have created a very simple function in the text editor and when I’m trying to use it with some arguments, it give an error.

In the text file kelvin.py I have:

def kelvin(tc):
 tk = tc + 273.15
 return tk

Python Console:

kelvin(23)
Traceback (most recent call last):
 File "<input>", line 1, in <module>
NameError: name 'kelvin' is not defined

Thanks for your time!!
