标题: int函数处理小数怎么不可以了呢？
[root@localhost opt]# cat input.py
#!/usr/bin/env python
num = raw_input("Enter a number:")
print int(num)
[root@localhost opt]# ./input.py
Enter a number:2.3
Traceback (most recent call last):
File "./input.py", line 3, in <module>
print int(num)
ValueError: invalid literal for int() with base 10: '2.3'

因为2.3是浮点数，不是整数
float(num)
