Creating letter patterns in Python is a great way to practice loops and ASCII manipulation. Below are examples of common letter patterns and their implementations.
1. Left-Aligned Triangle Pattern
This pattern prints letters row by row, starting from 'A'.
def left_triangle_pattern(rows):for i in range(rows):for j in range(i + 1):print(chr(65 + j), end="")print()left_triangle_pattern(5)Copied!âś•CopyOutput:
AABABCABCDABCDECopied!âś•Copy2. Right-Aligned Triangle Pattern
This pattern aligns the triangle to the right by adding spaces.
def right_triangle_pattern(rows):for i in range(rows):print(" " * (rows - i - 1), end="")for j in range(i + 1):print(chr(65 + j), end="")print()right_triangle_pattern(5)Copied!âś•CopyOutput:
AABABCABCDABCDECopied!âś•Copy3. Pyramid Pattern
A centered pyramid with letters expanding symmetrically.
def pyramid_pattern(rows):for i in range(rows):print(" " * (rows - i - 1), end="")for j in range(2 * i + 1):print(chr(65 + j), end="")print()pyramid_pattern(5)Copied!âś•CopyOutput:
AABCABCDEABCDEFGABCDEFGHICopied!âś•Copy4. Diamond Pattern
