I have code that manipulates data of a file that I currently have hard-coded in the script. I want to be able to prompt the user to chose the input file rather than having to hard-code it. Here is what I have for input. Instead of always using myfile.txt, I'd like the user to be able to choose the file:
with open('myfile.txt', 'rU') as input_file:
Use the input function on Python 3, or raw_input if you're using Python 2:
# Python 3
with open(input(), 'rU') as input_file:
# Python 2
with open(raw_input(), 'rU') as input_file:
This prompts the user for text input and returns it as a string. In your case, this will prompt for a file path to be input.
If you add an argument to this function, it prints something without a newline before input is requested, for example:
input("File: ")
Here's an example program which uses the input function:
answer = input()
print("Your answer was: " + answer)
When run:
foo
Your answer was: foo
