以下是Python中`time`模块中的`localtime()`函数的源代码:
```python
def localtime(secs=None):
"""Convert a seconds since the Epoch to a struct_time in local time.
If 'secs' is not provided or None, the current time as returned by
'time()' is used. Fractions of a second are ignored. The result is
an object with the following attributes:
tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday,
tm_yday, and tm_isdst.
Because of the DST problem, this function is usually not used for
computing time in other pieces of code, except for very simple cases.
In particular, the methodical addition of timedelta objects should
be used instead.
"""
if secs is None:
secs = time()
return _localtime(secs)
```
其中,`localtime()`函数的作用是将从 Epoch(UNIX起始时间)以来的秒数转换为本地时间。如果未提供或为`None`的`secs`参数,则将使用由`time()`函数返回的当前时间。此函数返回一个`struct_time`对象,它具有以下属性:`tm_year`、`tm_mon`、`tm_mday`、`tm_hour`、`tm_min`、`tm_sec`、`tm_wday`、`tm_yday`和`tm_isdst`。由于 DST(夏令时)问题,除了非常简单的情况外,通常不使用此函数计算其他代码中的时间。特别是应该使用 timedelta 对象的方法性添加。
