文本行对比，两个文件的

file = open('text3.txt', 'r', encoding='utf-8') # 生成没有空行的文件
file2 = open('sidh.txt', 'r', encoding='utf-8')

line = file.readlines()
line2 = file2.readlines()

def check(string, sub_str): 
    # if (string.find(sub_str) == -1): 
    if (string.find(sub_str)): 
        print("不存在！") 
    else: 
        print("存在！") 

for p in line:
	p = p.replace('[', '\[').replace(']', '\]').replace('
', '|')
	print(p,end='')
