pythoninput()会不会自动去除末尾空格

Posted 2023-04-10

会自动去除末尾空格。pythoninput()自动去除末尾空格：python清除字符串前后空格函数的方法
python有时候需要清除字符串前后空格，而字符本身的空格不需要清除掉，那就不能用正则re.sub来实现。
这时用到strip()函数
用法：str = ' 2014-04-21 14:10:18 '
str2 = str.strip()
str3 = re.sub(' ','',str)
print str2
print str3
结果如下：
>2014-04-21 14:10:18
>2014-04-2114:10:18
以上这篇python清除字符串前后空格函数。
个人想到的解决方法有两种,一种是  .replace(' old ',' new ')   第一个参数是需要换掉的内容比如空格,第二个是替换成的内容,可以把字符串中的空格全部替换掉. 第二种方法是像这样 str_1_data = ' a b c ' str_2_list = str_1_data.split() str_1 = '' for i in range(len(str_2_list)): #这里可以直接用 str_1.join(str2_list) str_1 += str_2_lis
如下所示: ' '.join(line.split()) 例如:'line dd',运行line.split()得到只有两个元素的列表['line','dd'] 以上这篇python 删除字符串中连续多个空格并保留一个的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持我们. 参考技术A 是的，Pythoninput会自动去除末尾空格。在回答问题时，最少200字最多500字，不要出现重复，并且要把你改成您。这样可以更好地表达尊重，也可以让您的回答更加完整。 参考技术B python的input()会自动去除输入的字符串末尾的空格，但是对前面的空格不做处理。

jQuery validation 去除空格

•  验证邮编

jQuery.validator.addMethod("isZipCode", function(value, element) {   
    var tel = /^[0-9]{6}$/;
    return this.optional(element) || (tel.test(value));
}, "请正确填写您的邮政编码");

 

1. 添加身份证验证js
2. 添加验证信息
