如何在字符串中的两个单词之间添加填充/边距？

word1 = "Hello"
word2 = "World"
padding = " " * 5  # 设置填充长度为5个空格
padded_string = word1 + padding + word2
print(padded_string)  # 输出：Hello     World

word1 = "Hello"
word2 = "World"
padding_char = "-"
padding_length = 10  # 设置填充长度为10个字符
padding = padding_char * padding_length
padded_string = word1 + padding + word2
print(padded_string)  # 输出：Hello-----World

word = "Hello"
padding_length = 10  # 设置填充长度为10个字符

left_padded_string = word.ljust(padding_length)
print(left_padded_string)  # 输出：Hello     

right_padded_string = word.rjust(padding_length)
print(right_padded_string)  # 输出：     Hello

center_padded_string = word.center(padding_length)
print(center_padded_string)  # 输出：  Hello
