Alphabet Pyramid Pattern

# Alphabet Pyramid Pattern by @CodingComputing
from string import ascii_uppercase as letters  # string of letters
height = 5  # given parameter
width = 1 + (height - 1)*2  # obtain the base width
for level in range(height):
    content = letters[:2*level+1]  # which letters to print
    print(f"{content:^{width}}")  # center within base width

# Output:
#     A
#    ABC
#   ABCDE
#  ABCDEFG
# ABCDEFGHI
