Using variables

Using variables

You're allowed to use as many variable declarations as you need to achieve your goa;, like this:

var = 1

account_balance = 1000.0

client_name = 'John Doe'

print(var, account_balance, client_name)

print(var)

You're not allowed to use a variable which doesn't exist (in other words, a variable that was not assigned a value).

This example will cause an error:

var = 1 print(Var)

We've tried to use a variable named Var, which doesn't have any value (note: var and Var are different entities, and have nothing in common as far as Python's concerned).

REMEMBER

You can use the print() function and combine text and variables using the + operator to output strings and variables, e.g.:

var = "3.8.5"

print("Python version: " + var)

Can you guess the output of the snippet above? 

Python version: 3.8.5
