Python reads files and simple use of time/sys module

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

The usage of some standard library functions also needs to be learned, such as: os/re/sets/string/queue/socket

Python code

#!/usr/bin/python  
  
print ord('a')  
print chr(97)  
#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()函数一次读入多行，循环输出  
for line in fp:  
  print line,

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]
