Why was .pyc file created?

Question

I created a file KingKong.py:

def KingKong():
print("Kingkong kingkong kingkong!")
input("King?")
print("Kong!")

if __name__ == "__main__":
print("Sorry")

Then I executed Kong.py:

import KingKong
KingKong.KingKong()

But why was KingKong.cpython-36.pyc created with text:

Answer 1

Python automatically compiles your script to compiled code, so called byte code, before running it.

When a module is imported for the first time, or when the source is more recent than the current compiled file, a .pyc file containing the compiled code will usually be created in the same directory as the .py file.

Answer 2

.pyc file is created on the first run and contains a bytecode: https://docs.python.org/3.5/glossary.html#term-bytecode

The structure of the bytecode may depend on interpreter used to run python code.

Answer 3

you can delete them no worries, they will spawn when needed
