Python: Only writes last line of output

Question

Trying to write a program that extracts URLs from a website. The output is good, but when I try to write the output to a file, only the last record is written. Here is the code:

Answer 1

You need to open you file then Write each X in the for loop.

At the end you can close the file.

f = open("f2.txt", "w+",1)

for x in extractUrls(url):
    print("-", x)
    f.write( x ) 

f.close()
