本文实例汇总了python中常用检测字符串相关函数。分享给大家供大家参考。具体分析如下:

下面的python代码可用于检测字符串,包括是否全部为数字,是否包含数字,是否包含标题单词,是否包含大写字母,是否包含小写字母,是否包含空格,是否以指定的字符开头和结尾。

my_string = "Hello World"
my_string.isalnum()   #检测所有字符是否都是数字
my_string.isalpha()   #检测字符串中的所有字符是否都是字母
my_string.isdigit()   #检测字符串是否包含数字
my_string.istitle()   #检测字符串是否包含标题单词
my_string.isupper()   #检测字符串是否包含大写字母
my_string.islower()   #检测字符串是否包含小写字母
my_string.isspace()   #检测字符串是否包含空格
my_string.endswith('d')   #检测字符串是否以字符d结束
my_string.startswith('H')  #检测字符串是否以大写字母H开头

下面显示返回结果

my_string="Hello World"
print my_string.isalnum()    #False
print my_string.isalpha()    #False
print my_string.isdigit()    #False
print my_string.istitle()    #True
print my_string.isupper()    #False
print my_string.islower()    #False
print my_string.isspace()    #False
print my_string.endswith('d')    #True
print my_string.startswith('H')   #True
