NameError: name 'randint' is not defined in Python

NameError: name 'randint' is not defined in Python #

The Python "NameError: name 'randint' is not defined" occurs when we use the randint function without importing it first. To solve the error, import the randint function before using it - from random import randint.

Here is an example of how the error occurs.

Copied!
# ⛔️ NameError: name 'randint' is not defined
n1 = randint(1, 10)

print(n1)

To solve the error, we have to import the randint function from the random module.

Copied!
# ✅ import randint function first
from random import randint

n1 = randint(1, 10)

print(n1)

Even though the random module is in the Python standard library, we still have to import it before using it.

Also, make sure you haven't imported randint in a nested scope, e.g. a function. Import the function at the top level to be able to use it throughout your code.

The random.randint function takes 2 numbers - a and b as parameters and returns a random integer in the range.

Note that the range is inclusive - meaning both a and b can be returned.

The random module is most commonly used to generate a random number from a range or select a random element from a sequence.

You can view all of the functions the random module provides by visiting the official docs.
