I'm expecting the following output
BANANA FRIES 12
POTATO CHIPS 60
APPLE JUICE 20
CANDY 20
However my code seems be returning incorrect value
Learn to debug. The incorrect value is the one for candy. First,
reduce you input to the candy lines. Still get wrong answer? Then
print the value in od within the loop after each calculation to see when
and how it goes wrong.
#!/usr/bin/env python3
import sys
import re
from collections import OrderedDict
if __name__ == '__main__':
od = OrderedDict()
recs = int(input())
for _ in range(recs):
file_input = sys.stdin.readline().strip()
m = re.search(r"(\w.+)\s+(\d+)", file_input)
if m:
if m.group(1) not in od.keys():
od[m.group(1)] = int(m.group(2))
else:
od[m.group(1)] += int(od.get(m.group(1),0))
for k,v in od.items():
print(k,v)
What's really going on here?
