input()

Theory

204/268

input() is built into Python. You do not import it. Freshers only need one honest call and the printed result — not a long definition.

Output — 22. Classroom stand-in for input() so the script always runs.

Wrong type often raises TypeError. Empty values matter for bool/all/any. Don’t mix input up with a similar name (sorted vs sort, int vs float).

Exam tip

Call input() once and say what prints.

# input()
s = "21"
n = int(s)  # same as int(input()) in class
print(n + 1)

Output: 22. Classroom stand-in for input() so the script always runs.
