How to start python or ipython with packages pre-imported.


This content originally appeared on DEV Community and was authored by Alexandre Bento Freire

Instead of every time you execute python or ipython, have to write “import os” or other common packages, this script will start python with these packages imported

#!/usr/bin/env bash
# -------------------------------------------------------------
#  Calls ipython or python3 with multiple packages imported
# -------------------------------------------------------------

if [[ -z "$1" ]] || [[ -f "$1" ]]; then
    [[ -n "$(command -v ipython3)" ]] && EXEC="ipython3" || EXEC=python3
    TMP_PY=/$TMPDIR/$EXEC.py
    printf "import os, re, sys, math, datetime, yaml\n" >$TMP_PY
    $EXEC -i $TMP_PY "$@"
else
    python3 "$@"
fi
