By admin|Computer, Python

Let’s say you have an associative array like: {“key1”: 22, “key2”: 42}

Then if you need to check key1 exists using python, following code will do that.

if key in array:
  # do something

Note: Be sure to put the key name in quotes if it’s a string.

Associative arrays are called dictionaries in Python and you can learn more about them in the stdtypes documentation
