I'm very new to Python and am working on some code to manipulate equations. So far, my code asks the user to input an equation. I want my code to be able to take something like "X + 1 = 2" and turn it into "x+1=2" so that the rest of my code will work, no matter the format of the entered equation.

A simple string .replace(old, new) followed by a .lower() will be sufficient.

"X + 1 = 2".replace(" ", "").lower() # 'x+1=2'
"X + 1   = 2".replace(" ", "").lower() # 'x+1=2'

for a more thorough replacement of all white space characters and not just spaces use python's re module:

import re 

re.sub(r'\s+', '', "X + 1   = 2").lower() # 'x+1=2'

To convert to lower case and strip out any spaces use lower and replace.

the_input = 'X + 1 = 2'

the_output = the_input.replace(' ', '').lower()

# x+1=2
