ValueError: invalid literal for int() with base 10: 'abc'

有时候需要用int()函数转换字符串为整型，但是切记int()只能转化由纯数字组成的字符串，如下例：

 1 Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32
 2 Type "copyright", "credits" or "license()" for more information.
 3 >>> str1='214567'
 4 >>> str2=''
 5 >>> str3='fsdf214356'
 6 >>> int(str1)
 7 214567
 8 >>> int(str2)
 9 Traceback (most recent call last):
10   File "<pyshell#4>", line 1, in <module>
11     int(str2)
12 ValueError: invalid literal for int() with base 10: ''#不可转换空字符串为整型
13 >>> int(str3)
14 Traceback (most recent call last):
15   File "<pyshell#5>", line 1, in <module>
16     int(str3)
17 ValueError: invalid literal for int() with base 10: 'fsdf214356'#不可转换非纯数字组成的字符串
 18 >>>

非纯数字组成的字符串强转为整型会报错：ValueError: invalid literal for int() with base 10
