如何使用循环将一系列字符映射到倒置的金字塔中？

def create_inverted_pyramid(chars):
    n = len(chars)
    inverted_pyramid = []
    
    for i in range(1, n+1):
        row_chars = ""
        char_count = 2 * i - 1
        
        for j in range(1, char_count+1):
            char_index = (j-1) % len(chars)
            row_chars += chars[char_index]
        
        inverted_pyramid.append(row_chars)
    
    return inverted_pyramid

# 示例调用
characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
result = create_inverted_pyramid(characters)
for row in result:
    print(row)
