In this tutorial, we will learn how to check if a number is a prime number in Python. We will cover the basic logic and conditions required to determine if a number is prime.

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. This means that a prime number cannot be formed by multiplying two smaller natural numbers.

The syntax to check if a number is prime in Python is:

```
def is_prime(number):
if number <= 1:
return False
for i in range(2, int(number**0.5) + 1):
if number % i == 0:
return False
return True
```

We can create a function to check if a given number is a prime number by testing its divisors.

For example,

- Define a function named
`is_prime`

that takes one parameter`number`

. - Check if the number is less than or equal to 1. If true, return
`False`

. - Use a
`for`

loop to iterate from 2 to the square root of the number (inclusive). - Check if the number is divisible by any of the values in the loop. If true, return
`False`

. - If the loop completes without finding any divisors, return
`True`

. - Call the function with a sample number and print the result.

```
def is_prime(number):
if number <= 1:
return False
for i in range(2, int(number**0.5) + 1):
if number % i == 0:
return False
return True
# Check if 29 is a prime number
result = is_prime(29)
# Print the result
if result:
print("29 is a prime number")
else:
print("29 is not a prime number")
```

29 is a prime number
