I recommend you to work onto code elegance. You can write x = input('prompt') instead of

print('prompt')
x = input()

And of course

	print("	1  implementation\n")
	print("	2  binary search\n")
	print("	3  math\n")
	print("	4  data structures\n")
	print("	5  dfs and similar\n")
	print("	6  graphs\n")
	print("	7  combinatorics\n")
	print("	8  constructive algorithms\n")
	print("	9  dp\n")
	print("	10 greedy\n")
	print("	11 strings\n")
	print("	12 hashing\n")
	print("	13 two pointers\n")
	print("	14 bitmasks\n")
	print("	15 sortings\n")
	print("	16 string suffix structures\n")
	print("	17 geometry\n")
	print("	18 dsu\n")
	print("	19 divide and conquer\n")
	print("	20 trees\n")
	print("	21 games\n")
	print("	22 probabilities\n")

can be replaced with

	for i in range(len(tags)):
		print('\t%-2d %s\n' % (i + 1, tags[i]))

I get this error when I tried it on windows
