创建一个脚本以打印出:字符之前的文本，每个输出在单独的一行中

import re

def print_text_before_character(text, character):
    lines = text.split('\n')
    for line in lines:
        match = re.search(character, line)
        if match:
            print(line[:match.start()])

# 示例用法
text = '''
This is line 1.
This is line 2.
This is line 3 with a character: X.
This is line 4.
'''
character = 'X'
print_text_before_character(text, character)

This is line 1.
This is line 2.
This is line 3 with a character:
