python字符串长度怎么调

# 字符连接original_string = "Hello"new_string = original_string + " World"print(len(new_string))  # 输出：11# 字符串重复repeated_string = original_string * 3print(len(repeated_string))  # 输出：15# 插值name = "Alice"interpolated_string = f"Hello, {name}!"print(len(interpolated_string))  # 输出：13# join() 函数list_of_strings = ["Hello", "World", "!"]joined_string = " ".join(list_of_strings)print(len(joined_string))  # 输出：13

# 字符串切片shortened_string = original_string[:-5]print(len(shortened_string))  # 输出：5# replace() 函数replaced_string = original_string.replace("Hello", "Goodbye")print(len(replaced_string))  # 输出：11# strip() 函数whitespace_string = "  Hello World  "trimmed_string = whitespace_string.strip()print(len(trimmed_string))  # 输出：12
