Hi everybody, I am new to Python, I try to understand how Python treats special characters. For example, if I execute the following line in a shell console, I obtain a colored string:
$ python -c "print '\033[30;44m foo \033[0m'" So, it works. Some time ago, I have made a lot of shell variables with all possible colors (with shell functions executed each time I launch a new shell). For example: $ echo -e $esc$ColorBlackOnDarkblue foo $esc$ColorReset gives the same result than the python command above. To know the corresponding non-interpreted characters, I can use the -n option of echo: $ echo -n $esc$ColorBlackOnDarkblue foo $esc$ColorReset \033[30;44m foo \033[0m So, it is exactly the string above, as expected. My problem arises when it comes to get these shell variables ( $esc, $ColorBlackOnDarkblue, $ColorReset) in a Python script, with os.environ, in the following 5-line script: import os Color = os.environ['ColorBlackOnDarkblue'] ColorReset = os.environ['ColorReset'] Esc = os.environ['esc'] print '%s%s%s%s%s' % (Esc, Color, " foo ", Esc, ColorReset) Run this script color.py, but after having defined these shell variables in a shell: $ export esc="\033" $ export ColorBlackOnDarkblue="[30;44m" $ export ColorReset="[0m" When I execute the Python script, I do not obtain any special character interpretation in Python: $ python color.py \033[30;44m foo \033[0m Why? What is the problem? Is there any solution? I really want to get my shell color variables. Thanks a lot -- TP (Tribulations Parallèles) "Allez, Monsieur, allez, et la foi vous viendra."
