Okay, first I will admit that I'm still digesting Danny Yoo's advice re: =
string interpolation. I will make attempts to use the technique he =
outlined some time today. What I'm up against right now has to do with =
appending to a file. My current code reads as follows:
#!/usr/bin/python
# append.cgi
# Author: Frik -- www.lowerstandard.com
# append data to a file, then print the data to screen
#
output =3D "no"
print "Content-type: text/html\n"
###
file =3D open('testdb.txt', 'w')
file.write(output)
###
print output
###
Although simple, this does exactly what I want it to do at this stage =
except for one little detail. If I hit this cgi it will write 'no' to my =
text file as it is supposed to, but I want to write to a new line rather =
than on the same line directly after the first. At present my text file =
which is being appended to reads=20
nonononono
What I want it to read as is
no
no
no
no
no
The obvious question, how do I write to a new line in an opened file?
TIA
