The built-in str() function allows you to create new strings and also convert other data types into strings: Python >>> str() '' >>> str(42) '42' >>> str(3.14) '3.14' >>> str([1, 2, 3]) '[1, 2, 3]' >>> str({"one": 1, "two": 2, "three": 3}) "{'one'...

print("datatype of num_new:",type(num_new)) 查看运行结果: 二、显式类型转换 显式类型转换 - 需要使用类型函数来转换 整型和字符串类型运算结果会报错,输出 TypeError。 Python 在这种情况下无法使用隐式转换,我们使用 int()、float()、str() 等预定义函数来执行显式类型转换 ...
a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable. Here are the details of Python data types ...
有序数据类型(sequence-based data types) 下标(index) 切片(slice) 1.数值(Number) 1.1 数值类型 Python的数值类型支持整数,浮点数和复数,他们在Python中分别是int,float和complex。 整数和浮点数的表面区别就是是否有小数点,有小数点的就是浮点数,没有的就是整数。整数可以为任意长度,浮点数只能保留小数点后15...
Dictionary (`dict`):An unordered collection of data stored as key-value pairs. Conversion Functions Python provides a suite of functions to convert between these types: –`int()`:Converts a value to an integer. –`float()`:Converts a value to a floating-point number. ...
Checking Data Types in Python Before converting data types, it’s useful to check them. Python provides two main functions: type(): Returns the type of a variable. isinstance(): Checks if a variable belongs to a certain type. a = 5.5 print(type(a)) # Output: <class 'float'> print(...
A tuple is a container which holds a series of comma-separated values (items or elements) between parentheses such as an (x, y) co-ordinate. Tuples are like lists, except they are immutable (i.e. you cannot change its content once created) and can hold mix data types....
