python vs julia

	python	julia	comment
	`print(1, 2)`	🤦‍♂️ `println(1, " ", 2)`	why I need to type `ln`?
slicing	👍 `a[::2]`	🤦‍♂️ `a[1:2:end]`	too verbose (start/stop must be given)
		🤦‍♂️ `sin.(a) .- 1`	silly dot
func def		👍 `f(x) = 2*x`
complex numbers	👍 `1j`	`1im`
		👍 `2x`	🤦‍♂️ `0x` `syntax: invalid numeric constant "0x"`

Sent files from command line to csv_plotter

	#! /usr/bin/env python3

	# Javascript only allows to fetch files from the local system by drag&drop.
	# Here a local server is setup to sent a file from command line to csv_plotter.
	# Furthermore, we also need to allow CORS...
	# The server closes finally; thus the browser cannot reload the url/file.

	# Example
	# ./csv_sent <filename>
