Can i use or in .replace function?

Question

I'm trying to make a temperature converter. It convert Celsius to Fahrenheit and vice versa. The code I wrote is:

user_input = input("Insert the temperature you would like to convert: ")
user_num = user_input.replace('F' or 'C', '')
user_temp = float(user_num)


if ('F' in user_input or 'f' in user_input):
  print(((user_temp - 32) * 5/9), 'C') # conversion from F to C

elif ('C' in user_input or 'c' in user_input): 
  print(((user_temp * 9/5) + 32), 'F') # conversion fron C to F

else: 
  print("Try again.")

Answer 1

'F' or 'C'<\/code> just evaluates to 'F'<\/code> . I don't think this is what you want. You can either replace twice:

user_num = user_input.replace('F', '').replace('C', '')

Answer 2

user_num = user_input.replace('F' or 'C', '')
