You can check if a variable is an integer using the type() function, passing the variable as an argument, and then comparing the result to the int class:age = 1 type(age) == int #TrueOr using isinstance(), passing 2 arguments: the variable, and the int class:...
Your input: 15The input is an integer: 15 In this example, we begin by obtaining a string input from the user using theinput()function, storing it in the variableuser_input. The subsequentifstatement checks if the input string is numeric using theisnumeric()method. ...
1.1 使用内置的type()函数 Python允许我们使用type()函数来检查变量的类型。例如: defcheck_type(variable):iftype(variable)isnotint:raiseTypeError("The variable must be an integer")returnvariableprint(check_type(10))# 输出: 10print(check_type("hello"))# 抛出异常 1. 2. 3. 4. 5. 6. 7. 2...
# variables a = 100 # an integer variable b = 10.23 # a float variable c = 'A' # a character variable d = 'Hello' # a string variable e = "Hello" # a string variable # checking types if isinstance(a, str): print("Variable \'a\' is a type of string.") else: print("...
