在Python中,你可以使用type()函数来检查变量的数据类型。例如: x = 100 print(type(x)) # 输出:<class 'int'> y = 3.14 print(type(y)) # 输出:<class 'float'> z = "Hello" print(type(z)) # 输出:<class 'str'> 了解这些基本数据类型对于编写Python代码非常重要,因为它们决定了你可以在变量中...
>>> print x ** 3 8000 >>> 1. 2. 3. 4. 5. 6. 7. 8. Now let see how we can use multiple variables for different values. So from above we know that x which represents value 20 and now we will take another variable called ‘y’ where we will assign value 10 to it and do...
