i want to know the difference between 'r' mode and 'r+' mode
1.i = open('c:\python25\integer.txt','w')-------->for writiing
i.write('hai')--------->written some content in text file
i = open('c:\python25\integer.txt','r')---->for reading
print i.read()---->for printing the contents in that text file
i = open('c:\python25\integer.txt','w')---------->for writing
i.write('how')-----------?Rewrite the contents
print i.read()
[MY QUESTION]:i want to read the text file contents cant it be done by
giving (print i.read())?
Before going to next question [I deleted all the contents in the text file]
2.i = open('c:\python25\integer.txt','r+')-----For reading and writing
i.write('hai')--------->written some content to text file
print i.read()--------->{Ø
†('c:\python25\integer.txt','w')
i write('')
print i.read()how')
i = open('c:\python25\integer.txt','r')
print i.read()
i = open('c:\python25\integer.txt','w')
i.write()
i = open('c:\python25\integer.txt','r')
print i.read() } --->Thats what i saw on
interpreter(In curly braces) when i ran the script
[MY QUESTION]:1.from where the above in curly braces is printed?and i have
written only 'hai' to the text file
2.Should i recall again the opening of the file in
'r' mode to read the file?
