os.remove() removes a file. os.rmdir() removes an empty directory. shutil.rmtree() deletes a directory and all its contents. Path objects from the Python 3.4+ pathlib module also expose these instance methods: pathlib.Path.unlink() removes a file or symbolic link. pathlib.Path.rmdir() removes an empty directory.
The first thing you should try is: On many environments that doesn’t work. So given the lack of info on that problem, I ended up removing pip manually from /usr/local/bin.
Having tested this using Python 3.5 and pip 7.1.2 on Linux, the situation appears to be this: pip install –user somepackage installs to $HOME/.local, and uninstalling it does work using pip uninstall somepackage. This is true whether or not somepackage is also installed system-wide at the same time. If the package is installed at both … Read more
To delimit by a tab you can use the sep argument of to_csv: To use a specific encoding (e.g. ‘utf-8’) use the encoding argument:
The correct, fully Pythonic way to read a file is the following: The with statement handles opening and closing the file, including if an exception is raised in the inner block. The for line in f treats the file object f as an iterable, which automatically uses buffered I/O and memory management so you don’t … Read more
You opened the file in binary mode: This means that all data read from the file is returned as bytes objects, not str. You cannot then use a string in a containment test: You’d have to use a bytes object to test against tmp instead: or open the file as a textfile instead by replacing … Read more
This question already has answers here: How to concatenate items in a list to a single string? How can I convert a list to a string using Python?
To understand what yield does, you must understand what generators are. And before you can understand generators, you must understand iterables. Iterables When you create a list, you can read its items one by one. Reading its items one by one is called iteration: mylist is an iterable. When you use a list comprehension, you … Read more
You need to add that folder to your Windows Path: https://docs.python.org/2/using/windows.html Taken from this question.
From the code you showed us, the only thing we can tell is that you are trying to create an array from a list that isn’t shaped like a multi-dimensional array. For example or will yield this error message, because the shape of the input list isn’t a (generalised) “box” that can be turned into … Read more
