Python lesson

Variables

= means 'store this value under this name'. Storing a new value replaces the old one, so the second print shows 40.

Example

A variable is a name that holds a value. You set it with =, then use the name instead of the value:

price = 35
print(price)
price = 40
print(price)

Output:

35
40

price = 35Store 35 in a variable called price. The name goes on the left.

print(price)No quotes, so Python looks up the value stored in price.

print("price")With quotes it's just text, so this shows the word price.

Names can use letters, numbers and underscores, like unit_price. No spaces.

Try each one in your head first, then open the answer.

1. Build a line that stores 35 in a variable called price.

price = 35

2. Build a line that shows the value stored in total.

print(total)

3. Create a variable called qty that holds 3, then print it.

qty = 3
print(qty)

4. Store the text Charger in a variable called product, then print product.

product = "Charger"
print(product)

5. Set city to Lagos. On the next line, change it to Abuja. Then print city.

city = "Lagos"
city = "Abuja"
print(city)
