write whitespace/tab to a text file

[dirkheld]

Hi,

I would l like to write some data to a text file. I want to write the
data with whitespace or tabs in between so that I create tabular
columns like in a spreadsheet. How can I do this in python.
(btw, I'm new to python)

names = ['John','Steve','asimov','fred','jim']
## output I would like in txt file : John Steve
asimov fred jim

f=open('/User/home/Documents/programming/python/test.txt','w')
for x in range(len(names)):
f.write(tags[x])
f.close()

Maybe :

names = ["Sebastien", "Ana", "Elodie", "Mohamed", "Antoniavna"]
maxlen = max(len(n) for n in names)
linetowrite = ""
for n in names:
linetowrite += n.ljust(maxlen + 3, ' ')
f = open('test.txt', 'w')
f.writelines(linetowrite.strip(' ') + '\n')
f.close()

f=open('/User/home/Documents/programming/python/test.txt','w')
for x in range(len(names)):
f.write(tags[x])
f.close()

Definitely consider the Python tutorial.

Also, please provide working code examples. I don't think yours will
work

names = ['John','Steve','asimov','fred','jim']
f = open('/User/home/Documents/programming/python/test.txt','w')
f.write('\t'.join(names))
f.close()

A better alternative could be the csv module.

I'm not sure exactly but you'll probably need to find out what the
ASCII code is for a tab. Personally I would just write data straight
into Excel using the win32 extensions. I'm sure the same can be
achieved with OO on a Linux box.

ASCII code is for a tab.

You don't need to know the ASCII code. Just use "\t":

print "%s\t%s\t%s" % (1,"two",3)

If you fixed column spacing with spaces instead of tabs:

print "%-8s%-8s%-8s" % (1,"two",3)
