错误记录：UnboundLocalError: local variable ‘time‘ referenced before assignment

def timetostr(timestamp):
    time = time.localtime(timestamp)
    datatime = time.strftime('%Y-%m-%d %H:%M:%S', time)
    return datatime

报错：

Traceback (most recent call last):
  File "E:\Py-Project\sample\main.py", line 18, in <module>
    print("建立时间：", timetostr(fileinfo.st_ctime))
  File "E:\Py-Project\sample\main.py", line 6, in timetostr
    time = time.localtime(timestamp)
UnboundLocalError: local variable 'time' referenced before assignment

也就是：赋值前引用的局部变量“time”

解决方法：修改变量名：

def timetostr(timestamp):
    loctime = time.localtime(timestamp)
    datatime = time.strftime('%Y-%m-%d %H:%M:%S', loctime)
    return datatime
