想要了解一个模块，help(module)获取详细文档

help(time)

help(re)

help(pandas)

快速获取模块包含的方法dir(module.function) 或者 module.function.__doc__

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

localtime(...)
    localtime([seconds]) -> (tm_year,tm_mon,tm_mday,tm_hour,tm_min,
                              tm_sec,tm_wday,tm_yday,tm_isdst)
    
    Convert seconds since the Epoch to a time tuple expressing local time.
    When 'seconds' is not passed in, convert the current time instead.
