 isdecimal()方法检查字符串是否仅由十进制字符组成。此方法只存在于unicode对象。

注意：要定义一个字符串为Unicode，只需前缀分配'u'左引号。以下是示例。
语法

以下是isdecimal()方法的语法：

str.isdecimal()
Copy after login

参数

  • NA

返回值

如果字符串中的所有字符为十进制此方法返回true，否则返回false。
例子

下面的例子显示了isdecimal()方法的使用。

#!/usr/bin/python


str = u"this2009"; 
print str.isdecimal();

str = u"23443434";
print str.isdecimal();
Copy after login

当我们运行上面的程序，它会产生以下结果：

False
True
Copy after login
