Carsten , I do not know python as well :-/


I found:
1. from python docs: http://docs.python.org/library/string.html

string.replace(str, old, new[, maxreplace])

Return a copy of string str with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

2.  while googling:

"Python like this:

python -c 'import sys; print sys.stdin.read().replace("\n", " ")' < days.txt"

http://linux.dsplabs.com.au/rmnl-remove-new-line-characters-tr-awk-perl-sed-c-cpp-bash-python-xargs-ghc-ghci-haskell-sam-ssam-p65/

3. also: http://bytes.com/topic/python/answers/721547-replace-characters-string

# >>> s = "sex_m-designer_bw-size_42"
# >>> s = s.replace('_', '=')
# >>> s = s.replace('-', '&')
# >>> s
# 'sex=m&designer=bw&size=42'

name-of-the-string.replace(' ', '.') # replace spaces with periods
