# Program to show various ways to read and 
# write data in a file. 

file1 = open("myfile.txt","w") 


L = ["This is Delhi \n","This is Paris \n","This is London \n"]  


  
# \n is placed to indicate EOL (End of Line) 

file1.write("Hello \n") 

file1.writelines(L) 

file1.close() #to change file access modes 


  

file1 = open("myfile.txt","r+")  


  

print "Output of Read function is "


print file1.read() 

print

  
# seek(n) takes the file handle to the nth 
# bite from the beginning. 

file1.seek(0)  


  

print "Output of Readline function is "


print file1.readline() 

print

  

file1.seek(0) 


  
# To show difference between read and readline 

print "Output of Read(9) function is "


print file1.read(9) 

print

  

file1.seek(0) 


  

print "Output of Readline(9) function is "


print file1.readline(9) 


  

file1.seek(0) 

# readlines function 

print "Output of Readlines function is "


print file1.readlines() 

print
file1.close()
