1 """Hook to allow user-specified customization code to run. 2 3 As a policy, Python doesn't run user-specified code on startup of 4 Python programs (interactive sessions execute the script specified in 5 the PYTHONSTARTUP environment variable if it exists). 6 7 However, some programs or sites may find it convenient to allow users 8 to have a standard customization file, which gets run when a program 9 requests it. This module implements such a mechanism. A program 10 that wishes to use the mechanism must execute the statement 11 12 import user 13 14 The user module looks for a file .pythonrc.py in the user's home 15 directory and if it can be opened, execfile()s it in its own global 16 namespace. Errors during this phase are not caught; that's up to the 17 program that imports the user module, if it wishes. 18 19 The user's .pythonrc.py could conceivably test for sys.version if it 20 wishes to do different things depending on the Python version. 21 22 """ 23 from warnings import warnpy3k 24 warnpy3k("the user module has been removed in Python 3.0", stacklevel=2) 25 del warnpy3k 26 27 import os 28 29 home = os.curdir # Default 30 if 'HOME' in os.environ: 31 home = os.environ['HOME'] 32 elif os.name == 'posix': 33 home = os.path.expanduser("~/") 34 elif os.name == 'nt': # Contributed by Jeff Bauer 35 if 'HOMEPATH' in os.environ: 36 if 'HOMEDRIVE' in os.environ: 37 home = os.environ['HOMEDRIVE'] + os.environ['HOMEPATH'] 38 else: 39 home = os.environ['HOMEPATH'] 40 41 pythonrc = os.path.join(home, ".pythonrc.py") 42 try: 43 f = open(pythonrc) 44 except IOError: 45 pass 46 else: 47 f.close() 48 execfile(pythonrc) 49
