Nim also has the in operator and it works similarly to Python.

Subtle difference: the negation of in in Python is not in (2 words), while in Nim it's notin (just 1 word).

Seq

seq
li = [5, 2, 8] print(2 in li) # True print(99 not in li) # True	let li = @[5, 2, 8] echo 2 in li # true echo 99 notin li # true # echo 99 not in li # ERROR (notice the space in "not in")

string
s = "C, C++, D, Nim" print("++" in s) # True print("--" in s) # False	import std/strutils # in operator let s = "C, C++, D, Nim" echo "++" in s # true echo "--" in s # false

𝥶Don't forget to import std/strutils. The in operator for strings comes from there!
