Last active August 29, 2015 14:22
A better way to print formatted floats using the `format()` specs.
def float_spec(fill, align, sign, width, separator, precision):
if len(fill) > 1:
raise ValueError('The fill character can only contain 1 character.')
if align not in ['left', 'right', 'center', 'padded']:
raise ValueError('{} is not an allowed alignment.'.format(align))
if sign not in ['+', '-', ' ']:
raise ValueError('{} is not a valid sign.'.format(sign))

Implement the Linux `which` command in Python that works in Windows!
import os
def which(executable):
for path in os.environ['PATH'].split(os.pathsep):
path = path.strip('"')
fpath = os.path.join(path, executable)
if os.path.isfile(fpath) and os.access(fpath, os.X_OK):
return fpath

Find all .py files that import a certain module or just supplied methods of the module. I use http://click.pocoo.org/ for interacting with the command line, but this can be changed.
import os
import re
from subprocess import PIPE, Popen
import click

Move seamlessly through paginated API results without loading all pages at once. Only loads the pages needed.
import math
def mceil(n, m):
'''
returns ceil(n) the multiple m.
example: mceil(21, 10) -> 30.0 which is the next multiple of 10.
:param n: value to ceil.

Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

Download GitHub repository, not a GIT clone command! This was the answer to a problem I was having, creating a skeleton app structure and easily setting up a local file structure. For example, obtaining the src directory from https://github.com/kamalgill/flask-appengine-template. This is a work in progress, not the prettiest of things.
'''

-h, --help show this help message and exit
