[SOLVED] Python Syntax Error

Gyroman · 10-07-2019, 07:00 AM

Very simple Python question

This code comes at the beginning of a program before a while statement

Code:

A = int(input("A ="))
N = int(input("N ="))

PrN = (1/A)*(((N-N/A)/N)
imp = 1/PrN

when run produces

Code:

imp = 1/PrN
  ^ Syntax Error

Why is this a syntax error?

Mismatched number of parentheses:

Whole thing is a mess.

Code:

>>> A = 5
>>> N = 2
>>> PrN = ((1/(A))*((N)-((N)/(A)))/(N))
>>> imp = (1/(PrN))
>>> print(imp)
6.249999999999999

Yes it was a mess but brackets around individual variables are unnesessary and confusing..

PrN = (1/A)*((N-N/A)/N)

works fine thank you.
