Python read-in files and simple use of time/sys modules

The use 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  #字符和整型互相转换    fp = open ("file.tmp")  for line in Fp.readlines ():    print line,  #文件操作readlines () function reads multiple lines at once, loops the output for the in  fp:    print,

Python code

#!/usr/bin/python  Import time  #time模块使用    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]
