    #文本内容
    Yesterday when I was young
    昨日当我年少轻狂
    The tasting of life was sweet
    生命的滋味是甜的
    As rain upon my tongue
    tasting
    I lived by night and shunned the naked light of day
    tasting123
    And only now I see how the time ran away
    tasting
    
    tasting
    

    将文本中的 tasting123删除 

    with open("fileread.txt","r",encoding="utf-8") as f:
    	lines = f.readlines()
    	#print(lines)
    with open("fileread.txt","w",encoding="utf-8") as f_w:
    	for line in lines:
    		if "tasting123" in line:
    			continue
    		f_w.write(line)
