Variables

A variable is a name that points to a value, so you can use and change it later.

• Create one with = : marks = 82.
• Names use letters, digits and _, and can't start with a digit.
• Giving a variable a new value replaces the old one.

marks = 82
marks = marks + 5
print(marks)

87

Remember: = means 'store this', not 'is equal to'.

Common mistake: Writing 2marks = 82. Names can't start with a digit.
