Can we use the update method in lists or other types of date?

If so, how?

[stetim94]

Which update method? Any docs to see which method you mean?

[gerardomtz_h]

Sure
This is an example of what I mean
In this case it is used to add multiple keys to a dictionary

user_ids = {"teraCoder": 9018293, "proProgrammer": 119238}

user_ids.update({'theLooper': 138475, 'stringQueen': 85739})

print(user_ids)

[stetim94]

methods are specific to data types. For list we could use extend

[jeannehemie]

Couldn’t we use .append()?

[mtf]

.append() is a list method. dict objects have no such method in their class.
