python中pprint

## pprint **(**pprint**)** ##

**pprint** is a python module that helps us to *make the readability of the complex data structures easy*. The **pprint** is also called as **"pretty print"**.

**pprint**是一个python模块，可帮助我们**简化** *复杂数据结构的可读性* 。 **pprint**也称为**“漂亮打印”** 。

Let us consider an example,

让我们考虑一个例子，

dictionary={
        'coord': {
        'lon': 77.22, 'lat': 28.67}, 
    'weather': [{
        'id': 721, 'main': 'Haze', 'description': 
    'haze', 'icon': '50d'}], 'base': 'stations', 'main': 
    {
        'temp': 44, 'feels_like': 40.42, 'temp_min': 44, 
    'temp_max': 44, 'pressure': 1002, 'humidity': 11}, 
    'visibility': 6000, 'wind': {
        'speed': 4.1, 'deg': 290, 
    'gust': 9.3}, 'clouds': {
        'all': 30}, 'dt': 1590398990, 
    'sys': {
        'type': 1, 'id': 9165, 'country': 'IN', 
    'sunrise': 1590364538, 'sunset': 1590414050}, 
    'timezone': 19800, 'id': 1273294, 'name': 'Delhi', 
    'cod': 200}
    
    # This is the dictionary that we wanted to print
    print(dictionary)

Now request module is of the article its just an example to create a nested data structure.

现在，本文的请求模块只是创建嵌套数据结构的一个示例。

**Output:**

**输出：**

{'coord': {'lon': 77.22, 'lat': 28.67}, 
    'weather': [{'id': 721, 'main': 'Haze', 'description': 'haze', 'icon': '50d'}], 
    'base': 'stations', 'main': {'temp': 44, 'feels_like': 40.42, 'temp_min': 44, 
    'temp_max': 44, 'pressure': 1002, 'humidity': 11}, 'visibility': 6000, 
    'wind': {'speed': 4.1, 'deg': 290, 'gust': 9.3}, 'clouds': {'all': 30}, 
    'dt': 1590398990, 'sys': {'type': 1, 'id': 9165, 'country': 'IN', 'sunrise': 1590364538, 'sunset': 1590414050}, 
    'timezone': 19800, 'id': 1273294, 'name': 'Delhi', 'cod': 200}

As you can see, the *output is not in a proper and readable way*, we cannot read this complex nested dictionary structure.

如您所见， *输出的格式不正确且可读* ，我们无法读取此复杂的嵌套字典结构。

To solve this issue of readability we will use the inbuilt module **pprint**.

为了解决此可读性问题，我们将使用内置模块**pprint** 。

## 下载pprint模块 **(**Downloading pprint Module**)** ##

**General way:** In your terminal or command prompt, type the following command,

**常规方法：**在终端或命令提示符下，键入以下命令，

pip install pprint

**Using pycharm:** Go to the project interpreter and install the module.

**使用pycharm：**转到项目解释器并安装模块。

Now after installing, import the module and there is a *function in this module named **pprint** so import that as*

现在，安装后，导入模块， *此模块中*有一个*名为**pprint***的*函数，因此将其导入为*

from pprint import pprint

To make the structure look good just **pprint()** instead of **print()**.

为了使结构看起来不错，只需使用**pprint()**而不是**print()即可** 。

# import pprint from the module pprint
    from pprint import pprint
    
    
    dictionary={
        'coord': {
        'lon': 77.22, 'lat': 28.67}, 
    'weather': [{
        'id': 721, 'main': 'Haze', 'description': 
    'haze', 'icon': '50d'}], 'base': 'stations', 'main': 
    {
        'temp': 44, 'feels_like': 40.42, 'temp_min': 44, 
    'temp_max': 44, 'pressure': 1002, 'humidity': 11}, 
    'visibility': 6000, 'wind': {
        'speed': 4.1, 'deg': 290, 
    'gust': 9.3}, 'clouds': {
        'all': 30}, 'dt': 1590398990, 
    'sys': {
        'type': 1, 'id': 9165, 'country': 'IN', 
    'sunrise': 1590364538, 'sunset': 1590414050}, 
    'timezone': 19800, 'id': 1273294, 'name': 'Delhi', 
    'cod': 200}
    
    # This is the dictionary that we wanted to print
    pprint(dictionary)

**Output:**

**输出：**

{'base': 'stations',
     'clouds': {'all': 30},
     'cod': 200,
     'coord': {'lat': 28.67, 'lon': 77.22},
     'dt': 1590398990,
     'id': 1273294,
     'main': {'feels_like': 40.42,
              'humidity': 11,
              'pressure': 1002,
              'temp': 44,
              'temp_max': 44,
              'temp_min': 44},
     'name': 'Delhi',
     'sys': {'country': 'IN',
             'id': 9165,
             'sunrise': 1590364538,
             'sunset': 1590414050,
             'type': 1},
     'timezone': 19800,
     'visibility': 6000,
     'weather': [{'description': 'haze', 'icon': '50d', 'id': 721, 'main': 'Haze'}],
     'wind': {'deg': 290, 'gust': 9.3, 'speed': 4.1}}

The above output is clear and it is easily readable.

上面的输出清晰易读。
