if is_float(some_string): some_string = float(some_string) elif some_string.isdigit(): some_string = int(some_string) else: print "Does not convert to int or float." This way you aren't accidentally converting what should be an int, into a float. Share Follow edited Oct 8, 2015...
Python中数字类型又包括:int(整型)、float(浮点型)和 complex(复数) print(type(123)) #<class 'int'> print(type(1.12)) #<class 'float'> print(type(3j + 1)) #<class 'complex'> 1. 2. 3. int(整型) 在32位机器上,整数的位数为32位,取值范围为 -2**31～2**31-1; 在64位系统上,整数...
1. 使用Python语言编写一个函数,接收一个整数和一个表示范围的字符串作为参数。 defcheck_range(num,range_str):start,end=map(int,range_str.split('-'))returnstart<=num<=end 1. 2. 3. 2. 在主程序中输入一个整数和一个范围字段,调用函数进行判断,并输出结果。 if__name__=='__main__':num=in...
Here, say_hello() and be_awesome() are regular functions that expect a name given as a string. The greet_bob() function, however, expects a function as its argument. You can, for example, pass it the say_hello() or the be_awesome() function....

这样更准确一些,适用性也更广。但如果你已经确信没有正负号,使用字符串的isdigit()方法则更为方便。 Python 字符串操作,如string替换、删除、截取、复制、连接、比较、查找、包含、大小写转换、分割等 代码语言:javascript 复制 deftest2():# 复制字符串 ...
