NameError: name ‘true’ is not defined. Did you mean: ‘True’?

In python NameError: name ‘true’ is not defined. Did you mean: ‘True’? we face this error message when we misspell True (capital T) Booleans as true (small t), and then python shows this error message. If you want to fix this error just type True (capital T) instead of (small t), For more clarification see the below example.

Wrong Code

n = int(input("Check this number:"))

def prime(number):
    for i in range(2, number):
        is_prime = true
        for i in range(2, number):
            if number % i == 0:
                is_prime = False
        if is_prime:
            print("It's a prime number.")
        else:
            print("It's not a prime number.")


prime(number = n)

• Wrong action: true (small t).
• Correct action: True (capital T)

Entire Correct Code line

n = int(input("Check this number:"))

def prime(number):
    for i in range(2, number):
        is_prime = True
        for i in range(2, number):
            if number % i == 0:
                is_prime = False
        if is_prime:
            print("It's a prime number.")
        else:
            print("It's not a prime number.")


prime(number = n)
