在Python中将int转换为字符串 [英] Casting an int to a string in Python

问题描述

我希望能够生成一些名称为fileX.txt的文本文件，其中X是一个整数：

I want to be able to generate a number of text files with the names fileX.txt where X is some integer:

for i in range(key):
    filename = "ME" + i + ".txt" //Error here! Can't concat a string and int
    filenum = filename
    filenum = open(filename , 'w')  

有没有其他人知道怎么做filename =ME+我的部分，所以我得到一个名称为ME0.txt，ME1.txt，ME2的文件列表。 txt，等等

Does anyone else know how to do the filename = "ME" + i part so I get a list of files with the names: "ME0.txt" , "ME1.txt" , "ME2.txt" , and etc

推荐答案

x = 1
y = "foo" + str(x)
