# Variables in Python

In the previous exercise, we have seen Python is a great calculator. In real-life when we write code, we use variables to define values so that we can reuse them again and again in our code.

A variable is a name that refers to a value. Let's see some examples.

``````my_name = "John"
age = 28
pi = 3.14
``````

Here `John` is a string which is assigned to `my_name` variable. Similarly `28` is a number which is assigned to variable `age`. Variable `pi` is assigned the value of `3.14`

Pro Tip - `=` is an assignment operator in Python. You can assign a value to a variable using `=` operator

### Display value of a variable

To print the value of a variable, we use `print` statement. To print the value of `my_name` and `pi`, simply type below statement into a Jupyter notebook on the right-hand side and execute the cells.

``````print(my_name)
print(pi)
``````
INSTRUCTIONS

Use Jupyter notebook on the right-hand side to write code and complete this exercise

• Define variable `bank_balance` with the value `200`
• Print value of `bank_balance`. It should print `200`
