Installing Packages¶. This section covers the basics of how to install Python packages. It’s important to note that the term “package” in this context is being used as a synonym for a distribution (i.e. A bundle of software to be installed), not to refer to the kind of package that you import in your Python source code (i.e. A container of modules). The path list contains a list of directory names where Python looks for extension modules (Python source modules, compiled modules, or binary extensions). When you start Python, this list is initialized from a mixture of built-in rules, the contents of the PYTHONPATH environment variable, and the registry contents (on Windows). The value of sys.modules is a dictionary mapping the names of modules to modules which have already been loaded. This can be manipulated e.g. To enforce the reloading of modules. Note that removing a module from this dictionary is not the same as calling reload() on the corresponding module object.
I am new to python and I have a question about a piece of python code that creates a cleaned up output file from a model output file. This code was written for a Mac user, but now I want to run it in Windows. But it gives an error message. Could you help me in converting this code so I can use it in Windows? Import sys if len(sys.argv) > 1: fileName = sys.argv[1] else: print 'selected_um_b.out' #insert file name here sys.exit() f = open(fileName) counter = 0 fw = open(fileName+'.cleaned', 'w') for line in f: line = line.strip() counter = counter + 1 if counter. The program expects a filename on the command line when you execute it. It appears you did not provide one, so the program exited (the sys.exit() call terminates the program).
How are you trying to use it? If you just want to convert one file, put the file and the Python script into the same directory. Replace lines 3 through 7 with filename = 'yourfilename.typ' (do not indent the line); it will read the file ('yourfilename.typ' in my example) and write an output file with 'cleaned' in the filename. The line values = line.split(' t') splits input lines (after the 4th line) into chunks that are separated by tabs.
(That's what the backslash-t means - a tab). The parts are put into the 'values' variable, which will be an array (actually a list, but you can think of it as an array). The likely problem is that some line contains fewer than 6 chunks; the values[4] and values[5] pick the 5th and 6th chunks from the array.

Modules and Imports Most Python programs end up as a combination of several modules with a main application importing them. Whether using the features of the standard library, or organizing custom code in separate files to make it easier to maintain, understanding and managing the dependencies for a program is an important aspect of development. Includes information about the modules available to an application, either as built-ins or after being imported. It also defines hooks for overriding the standard import behavior for special cases. Import sys import os base_dir = os. Dirname ( __file__ ) or '.'
Print 'Base directory:', base_dir # Insert the package_dir_a directory at the front of the path. Package_dir_a = os. Join ( base_dir, 'package_dir_a' ) sys. Insert ( 0, package_dir_a ) # Import the example module import example print 'Imported example from:', example. __file__ print ' t ', example. DATA # Make package_dir_b the first directory in the search path package_dir_b = os.

Join ( base_dir, 'package_dir_b' ) sys. Insert ( 0, package_dir_b ) # Reload the module to get the other version reload ( example ) print 'Reloaded example from:', example. __file__ print ' t ', example. DATA Reloading an imported module re-imports the file, and uses the same module object to hold the results. Changing the path between the initial import and the call to reload() means a different module may be loaded the second time. Import sys class NoisyImportFinder ( object ): PATH_TRIGGER = 'NoisyImportFinder_PATH_TRIGGER' def __init__ ( self, path_entry ): print 'Checking NoisyImportFinder support for%s '% path_entry if path_entry!= self.
