Topics to be covered
● Passing Strings to function
● Passing Lists to function
● Passing Tuples to function
● Passing Dictionaries to function
Presented by : S K Mahto, PGT Computer Science

Passing String to a Function
● String can be passed in a function as argument but it is used as pass by
value. It can be depicted from below program. As it will not change value of
actual argument.
Output :
Sanjay

Passing List to a Function
● List is mutable data type that’s why it treat as pass by reference.
● It is already discussed in topic Mutable/immutable properties of data
objects.
Output

Passing Tuple to a Function
● In function call, we have to explicitly define/pass the tuple. It is not required
to specify the data type as tuple in formal argument.
Output
3

Passing Dictionary to a Function
