python中使用replace替换多个字符的方法：
1、使用replace方法替换多个相连的字符
#!/usr/bin/python
str = "this is string example....wow!!! this is really string";
print str.replace("is", "was");
print str.replace("is", "was", 3);输出结果如下：
thwas was string example....wow!!! thwas was really string
thwas was string example....wow!!! thwas is really string
2、在replace()函数中使用正则替换多个字符
//定义一个数组 let str = [[1],[2],[3],[4]]; //先转换成JSON字符串 let str2 = JSON.stringify(str); //在对该字符串进行字符替换,在这里我们将所有中括号都替换成空 console.log(str2.replace(/\[|]/g,'')); //这样就完成了多个字符的替换
