Question

I am trying to replace some text in a file with python 2.6

However, it returns an extra newline here is my code:

for line in fileinput.input('/etc/php5/apache2/php.ini', inplace=True):
   replace = re.sub(r'(post_max_size =).[0-9]+(M)', r'\1 64\2', line)
   print replace

Input:

post_max_size = 6M
sdfsdfsd
post_max_size = 4M
sdfsdf
post_max_size = 164M
dfsdfsdfsdfsdf

output:

post_max_size = 64M

sdfsdfsd

post_max_size = 64M

sdfsdf

post_max_size = 64M

dfsdfsdfsdfsdf

Answer 1

Try:
print replace, instead. The trailing comma suppresses the newline (but adds a trailing space). For complete control use the print function from __future__ instead.
