Simple python script to print Desmos function to inputed power,

desmos-power.py

#!/usr/bin/env python3
# Accepts only positive and negative integters

power, eq = int(input("Highest power of function: ")), ""
power_l = list(range(abs(power)))

for i in range(len(power_l)):
	last_item = power_l.pop()
	power_l.insert(i, last_item + 1)

for i in power_l:
	if power < 0: # negative powers
		eq = eq + "\\frac{a_{" + str(i) + "}}{x^{" + str(i) + "}}+"
	else: # positive powers
		eq = eq + "a_{" + str(i) + "}x^{" + str(i) + "}+"

print("Desmos function: " + eq + " b")
