If you want to specify the data type of a variable, this can be done with casting. Example x =str(3)# x will be '3' y =int(3)# y will be 3 z =float(3)# z will be 3.0 Try it Yourself » Get the Type You can get
The ___ function is used to determine the type of a variable in Python. The ___ function can be used to check if a variable is of a specific type in Python. If we want to check the type of a variable `x`, we can use ___ to get the result. ...
浮点型(float): 浮点型由整数部分与小数部分组成,浮点型也可以使用科学计数法表示(2.5e2 = 2.5 x 102 = 250) 复数(complex): 复数由实数部分和虚数部分构成,可以用a + bj,或者complex(a,b)表示, 复数的实部a和虚部b都是浮点型。 我们也可以使用十六进制和八进制代表整数: 代码语言:javascript 代码运行次数:...
得到一个字典里所有的值,除此之外,我们还可以使用get()来返回字典里具体键名对应的值,get()返回的值是所导入的键名对应的值, 举例如下: >>> print dict {'Vendor': 'Cisco', 'IOS: '12.2(55)SE12', 'CPU': 36.3, 'Model': 'WS-C3750E-48PD-S'} >>> dict.get('Vendor') 'Cisco' >>> ...
To achieve our goal, we’ll use theindexmethod which is a function associated with a specific class and serves for a certain function when attached to a variable following a dot. Theindexmethod in particular, returns the index of the given substring, inside the string.The substring that we ...
