Long lines of code

Long lines of code that have parentheses (round brackets) can be split over multiple lines.

print(1 + 2 +
      3 + 4)

print('Long lines of code '
      'can be broken up.')

Long lines of code without parentheses can use a backslash (\) to split them.

answer = 1 + 2 \
         + 3 + 4

print(answer)

f Strings

pi = 3.14159265359

print(f'pi = {pi}')

print(f'pi = {pi:.4f} (4 dp)')

print(f'pi = {pi:.4g} (4 sf)')

print(f'Enjoy a raspberry pie for only £{pi*2:.2f}!')

Combined Operators

Arithmetic operators can be combined with the assignment operator.

Operator	Example	Meaning
+=	x += 3	x = x + 3
-=	x -= 3	x = x - 3
*=	x *= 3	x = x * 3
/=	x /= 3	x = x / 3
%=	x %= 3	x = x % 3
//=	x //= 3	x = x // 3
**=	x **= 3	x = x ** 3
