# `man` for python functions
|
|
#
|
|
# A few libraries are imported by default:
|
|
# <name>/[alias]
|
|
# numpy/np
|
|
# pandas/pd
|
|
print_help() {

cat <<HELP
|
|
Open the help page for a python function
|
|
|
|
Usage: $(basename $0) [options] <function>
|
|
|
|
Options:
|
|
--lib <lib> Specify a library to import
|
|
|
|
Numpy as np and Pandas as pd work by default. Prefixing with a library works
|
|
|
|
Examples:
|
|
$(basename $0) exit
|
|
$(basename $0) --lib os os.getcwd
|
|
$(basename $0) os.getcwd # Implicity imports \`os\`
|
|
$(basename $0) numpy.random.randint # Implicity imports \`numpy.random\`
|
|
$(basename $0) np.random.randint # np -> numpy, then same as above
