1. Building a Pyramid in Python?

Simple Number pyramid

n = 5

for i in range(1, n + 1):

    print(" " * (n - i), end="")

    for j in range(1, i + 1):

        print(j, end=" ")

    print()

Output:

    1

   1 2

  1 2 3

 1 2 3 4

1 2 3 4 5

2. Counting Digits, Letters, and Spaces in a String?

text = input("Enter a string: ")

letters = 0

digits = 0

spaces = 0

others = 0

for char in text:

    if char.isalpha():

        letters += 1

    elif char.isdigit():

        digits += 1

    elif char.isspace():

        spaces += 1

    else:

        others += 1

print("Letters:", letters)

print("Digits:", digits)

print("Spaces:", spaces)

print("Other characters:", others)

Example: Hello World 123!

The output is:

Letters: 10

Digits: 3

Spaces: 2

Other characters: 1
