5. fromtimestamp（sec）： - 返回自参数中提到的epoch以来经过的秒数计算的日期。

6. min（）： - 返回日期类可以表示的最小日期。

7. max（）： - 返回日期类可以表示的最大日期。

# Python code to demonstrate the working of

# fromtimestamp(), min() and max()

# importing built in module datetime

import datetime

from datetime import date

# using fromtimestamp() to calculate date

print ("The calculated date from seconds is : ",end="")

print (date.fromtimestamp(3452435))

# using min() to print minimum representable date

print ("Minimum representable date is : ",end="")

print (date.min)

# using max() to print minimum representable date

print ("Maximum representable date is : ",end="")

print (date.max)

输出:

The calculated date from seconds is : 1970-02-09
Minimum representable date is : 0001-01-01
Maximum representable date is : 9999-12-31
