Simple use of python to read files and the time/sys module

Python reads files and timesys modules. the usage of some standard library functions is also to be learned, such as osresetsstringqueuesocket #!

Usage of some standard library functions is also to be learned, such as: OS/re/sets/string/queue/socket

Python code

#! /Usr/bin/python print ord ('A') print chr (97) # Conversion between characters and integers fp = open ("file. tmp ") for line in fp. readlines (): print line, # The File operation readlines () function reads multiple rows at a time, and cyclically outputs for line in fp: print line,

Python code

#! /Usr/bin/python import time # time module uses print time. localtime (). tm_year # time. struct_time (tm_year/tm_mon/tm_mday/tm_hour/tm_min/tm_sec/# tm_wday/tm_yday/tm_isdst) print time. asctime () # time () localtime () gmtime () ctime () strftime () strptime () # clock () sleep ()

Python code

#!/usr/bin/python  import sys    print sys.platform  print sys.argv[0]  print sys.argv[1]
