python中int函数

Python int()函数 (Python int() function)

int() function is used to convert a string (that should contain a number/integer), number (integer, float) into an integer value.

int()函数用于将字符串(应包含数字/整数)，数字(整数，浮点数)转换为整数值。

Syntax:

句法：

    int(value, [base=10])

Parameter:

参数：

• value – source value (string, number(integer/float)) to be converted in an integer value.

  value –要转换为整数值的源值(字符串，数字(整数/浮点数))。

• base – it’s an optional parameter with default 10, it is used to define the base of source value, for example: if source string contains a binary value then we need to use base 2 to convert it into an integer.

  base –这是一个可选参数，默认值为10，用于定义源值的基数，例如：如果源字符串包含二进制值，则需要使用基数2将其转换为整数。

Return value: int – returns an integer value.

返回值： int –返回一个整数值。

Example:

例：

    Input:
a = "1001"
print(int(a))
Output:
1001
Input:
a = 10.23
print(int(a))
Output:
10
Input:
a = "1110111"
print(int(a,2))
Output:
119

Python code to convert values to an integer

Python代码将值转换为整数

# python code to demonstrate example
# of int() function
a = 10.20
b = "1001"
c = "000"
print("a: ", a)
print("int(a): ", int(a))
print("b: ", b)
print("int(b): ", int(b))
print("c: ", c)
print("int(c): ", int(c))

Output

输出量

a:  10.2
int(a):  10
b:  1001
int(b):  1001
c:  000
int(c):  0

Python code to convert different numbers systems (binary, octal and hexadecimal) to integer value (decimal)

Python代码可将不同的数字系统(二进制，八进制和十六进制)转换为整数值(十进制)

# python code to demonstrate example
# of int() function
a = "10101010"
print("a: ", int(a,2))
a = "1234567"
print("a: ", int(a,8))
a = "5ABC12"
print("a: ", int(a,16))

Output

输出量

a:  170
a:  342391
a:  5946386
