Check if the input is a number using int() or float() in Python Theint()orfloat()method is used to convert any input string to a number. We can use this function to check if the user input is a valid number. If the user input is successfully converted to a number usingint()orfl...
第一,input()用于获取键盘上的输入,该函数的返回值是一个Python字符串str类型的数据——不过输入的是什么;第二,float()函数用于将传递的参数——这里就是input()的返回值,一个字符串——转换为float浮点数的类型。float()函数转换input()的返回值相对于使用int()可以保留相应的精度。 float(input())在web中的...

我想使用if else检查python中的数据类型 我想要的输出:如果用户输入float数据类型以打印It is float,或者如果用户输入另一个Datatype,以打印it is not float Code: c=(input("Enter the value\n")) if type (c) == float: print('it is float') ...
二、基本类型-int、float、bool、None 1、int int(),可以对浮点数进行去整操作,可将数字字符串转换成整形。与input结合使用来获取用户的数值输入。 x = 3 # 定义变量 x = int(3.14) # 3 x = int("123") # 123 type(x) is int # True
