Python_write和writelines的区别

Python_write和writelines的区别

1 write()需要传入一个字符串做为参数,否则会报错

2 writelines()既可以传入字符串又可以传入一个字符序列,并将该字符序列写入文件

  注意 ：writelines必须传入的是字符序列,不能是数字序列
              如：list_1023 = [1,2,3,4,5]

报错:TypeError: write() argument must be str, not list

1、write():

fp = open("1023bb.txt","w+")
l = ["1023","1024","1025"]
fp.write(l)
fp.seek(0,0)
fp.read()
fp.close()

 

运行报错:TypeError: write() argument must be str, not list

 

2、writelines()

fp = open("1023bb.txt","w+")
l = ["1023","1024","1025"]
fp.writelines(l)
fp.seek(0,0)
fp.read()
fp.close()

 

则执行成功。

执行效果如下:
