# Take n
n = int(input("Enter n: "))

# Print factorials
for i in range(1, n + 1):
    fact = 1
    for j in range(1, i + 1):
        fact *= j
    print(f"{i}! = {fact}")

Output

Enter n: 5
1! = 1
2! = 2
3! = 6
4! = 24
5! = 120

Calculate factorial for each number.

Key Concepts:

Outer loop: numbers 1 to n
Inner loop: calculate factorial
Print each factorial
