Решение: https://pastebin.com/SVb1T8qU
Предлагам и моето решение с именовани групи и с по-краткия вариант на регекса:
import re
pattern = re.compile(
r'%(?P<customer>[A-Z][a-z]+)%.*?'
r'<(?P<product>\w+)>.*?'
r'\|(?P<count>0|[1-9]\d*)\|.*?'
r'(?P<price>(0|[0-9]\d*)(\.\d+)?)\$'
)
total_income = 0.0
while (string := input()) != 'end of shift':
m = pattern.search(string)
if m:
total_price = int(m.group('count')) * float(m.group('price'))
total_income += total_price
print(f"{m.group('customer')}: {m.group('product')} - {total_price:.2f}")
print(f'Total income: {total_income:.2f}')
