python模块sys

## Python sys模块 **(**Python sys Module**)** ##

The **sys module** provides us the information about the Python interpreter that is used to interact with the Python interpreter. This module is one of the best modules of Python and to use the sys module, we have to import it in the program like other inbuilt modules. This provides a lot of information about the Python interpreter such as the version of the interpreter, the max value that a variable can store, information about the copyright of the Python interpreter, etc. Here, we will see some important functions of the **sys module** with an example.

**sys模块**为我们提供了有关与Python解释器进行交互的Python解释器的信息。 该模块是Python最好的模块之一，要使用sys模块，我们必须像其他内置模块一样将其导入程序中。 这提供了许多有关Python解释器的信息，例如解释器的版本，变量可以存储的最大值，有关Python解释器的版权的信息，等等。在这里，我们将看到**sys模块的**一些重要功能。举个例子。

### sys模块的一些重要功能 **(**Some important function of the sys module**)** ###

### 1)系统版本 **(**1) sys.version**)** ###

This function returns a string representing the version of the Python interpreter with the date of the installation.

此函数返回一个字符串，该字符串表示Python解释器的版本以及安装日期。

**Example:**

**例：**

# Importing the module
    import sys
    
    # Printing the python version
    print(sys.version)

**Output**

**输出量**

3.7.1 (default, Dec 10 2018, 22:54:23) [MSC v.1915 64 bit (AMD64)]

### 2)系统版权 **(**2) sys.copyright**)** ###

This function returns information about the copyright of the Python interpreter.

此函数返回有关Python解释器版权的信息。

**Example:**

**例：**

# Importing the module
    import sys
    
    # Printing the copyright information
    print('Information about the copyright:')
    print(sys.copyright)

**Output**

**输出量**

### 3)sys.maxsize **(**3) sys.maxsize**)** ###

This function returns the maximum value of integer that a variable can take.

此函数返回变量可以采用的整数的最大值。

**Example:**

**例：**

# Importing the module
    import sys
    
    # Printing the max value of an integer
    print('Maximum value of an integer:',sys.maxsize)

**Output**

**输出量**

Maximum value of an integer: 9223372036854775807

### 4)系统路径 **(**4) sys.path**)** ###

This function returns a list that contains the search path for all Python modules.

此函数返回一个列表，其中包含所有Python模块的搜索路径。

**Example:**

**例：**

# Importing the module
    import sys
    
    # Printing the all path
    print('List of the all path:')
    print(sys.path)

**Output**

**输出量**

List of the all path:['/home/runner', '/usr/local/lib/python37.zip', 
    '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', 
    '/home/runner/.local/share/virtualenvs/python3/lib/python3.7/site-packages']
