Python小白进阶计划（一）之如何了解库的函数及用法

安装好了Anaconda,开始一点点了解什么是Python,所以记录应该会很杂，以后会统一整理的，估计得等到我真正觉得自己入门的时候吧。

查看库函数及属性
1.window+R打开cmd,运行python
2.import 库名
3.查看库dir(库名)
4.了解库help(库名)
5.了解库函数help(库名.函数)

接下来是操作及结果样式

D:\>python
Python 3.8.3 (default, Jul  2 2020, 17:30:36) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

>>> import time
>>> dir(time)
['_STRUCT_TM_ITEMS', '__doc__', '__loader__', '__name__', '__package__', '__spec__', 'altzone', 'asctime', 'ctime', 'daylight', 'get_clock_info', 'gmtime', 'localtime', 'mktime', 'monotonic', 'monotonic_ns', 'perf_counter', 'perf_counter_ns', 'process_time', 'process_time_ns', 'sleep', 'strftime', 'strptime', 'struct_time', 'thread_time', 'thread_time_ns', 'time', 'time_ns', 'timezone', 'tzname']
>>> help(time.sleep)
Help on built-in function sleep in module time:

sleep(...)
    sleep(seconds)

    Delay execution for a given number of seconds.  The argument may be
    a floating point number for subsecond precision.

>>> help(time)
Help on built-in module time:
