Below is the code which can be helpful for better insight:
Sample: 1
For the below code, you can provide initially the number of entries
(say 4) so that for four times name of person and age is prompted to
enter.After writing to file we can read back the contents
#Writing number of times the nam
If you're using this as an interactive command to help you populate a
database, as you appear to be, don't open the file more than once. As
previously suggested you should also put all your strings together and
then write them to the database in one go.
I don't know if you've thought about this ye

It might be that when you create a file for the first time with 'a', that
it
will through an exception. So you will have to try with 'w', and if there
is
an exception, you know the file does not exist and you will have to
create
the file for the first time with 'w'.

i need it to be able to add more entries instead of just one.
my code is like this:
while True:
name = raw_input("what is the name ")
age = raw_input("what is the age ")
out_file = open("persons.txt", "w")
It would work if you moved the open() call ou

Thanx, you are correct. And now I know that 'a' will create a file as well.

Hi,
It is the way you open the text file in the beginning.
This is from the python manual:
open() returns a file object, and is most commonly used with two arguments:
"open(filename, mode)".
>>> f=open('/tmp/workfile', 'w')
>>> print f
The first argument is a string containing the filename. T
