The very first line of your function km_mi(): ends it:
def km_mi():
return answer
answer has not been assigned, so it returns None.
Advice: remove that "return" line from there. Also get rid of the last line,
answer = km_mi which makes answer refer to the function km_mi().
Put the "return answer" line at the end, where the "answer=km_mi" used to be.
That should help. The code calculates "answer". It prints "answer". You
should return "answer" at the end, after it has been calculated.

Subject: Output showing "None" in Terminal
Hi!
i'm new to python and would like some help with something i was working on from
a tutorial. I'm using VScode with 3.7.0 version on Windows 7. Below is my code
and the terminal is showing the word "None" everytime I execute my code.
Many thanks!
print("Conversion")
def km_mi():
return answer
selection = input("Type mi for miles or km for kilometers: ")
if selection == "mi":
n = int(input(print("Please enter distance in miles: ")))
answer = (1.6*n)
print("%.2f" % answer, "miles")
else:
n = float(input(print("Please enter distance in kilometers: ")))
answer = (n/1.6)
print("%.2f" % answer, "kilometers")
answer = km_mi
