Question

Is there a way to save data after it was printed to the screen?
for example:
lets have some arbitrary function

def main():
    if something:
       for i in range(n):
           output= "%f %f" %(n,d)
           print output

    if something:
       for i in range(n):
           output="%f %f" %(n,d)
           print output

    fileout=open("data.csv", "a")
    fileout.write(output)

this will only write the last data for the last range in for loop.

Edit: I want to ask a user if she/he wants to save that data

Answer 1

Declare your output variable(s) at the highest level of scope in your program first. This will allow it to be written to a file in the manner you’ve programmed.

If you want to prompt a user for a location to save the file(s), that’s merely this:

out1 = raw_input("Where would you like to save this? ")

You can do the same for another output file variable.
