In Python we frequently need to check if a value is in an array (list) or not. Python x in list can be used for checking if a value is in a list. Note that the value type must also match. Here is a quick example:
a = ["1", "2", "3"] if "2" in a: print "string 2 is in array a" else: print "string 2 is not in array a" if 2 in a: print "number 2 is in array a" else: print "number 2 is not in array a"
string 2 is in array a number 2 is not in array a
Env: Python 2.7.18
