2. Working with Functions
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

3. Working with Functions
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.

4. Working with Functions
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.
Presented by : S K Mahto, PGT Computer Science

5. Working with Functions
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.

6. Working with Functions
Passing Dictionary to a Function
● In Python, everything is an object, so the dictionary can be passed as an
argument to a function like other variables are passed.
