I am trying to calculate the scores entry for people from a text file:
essi 5 pietari 9 essi 2 pietari 10 pietari 7 aps 25 essi 1
output expected:
Contestant score: aps 25 essi 8 pietari 26
my output: aps 25 essi 11 pietari 77
my code calculation is wrong!
my code is:
def reading():
"""
reads input file name and open it, split lines from text in 2.
do the calculation, print out the dictionary
:return: dict.
"""
file1 = input("Enter the name of the score file: ")
read_file = open(file1, mode="r")
dict = {}
for line in read_file:
# Remove the character(s) that end the line.
line = line.rstrip()
# Split the line in two.
name, score = line.split(" ")
# Add a new entry to the phone book.
if name not in dict:
dict[name] = score
elif name in dict:
dict[name] = score + score
#Close the file.
read_file.close()
#print dict sorted
for p in sorted(dict.keys()):
print(f"{p} {dict[p]}")
def main():
#the function call
reading()
if __name__ == "__main__":
main()
Try the below. (zz.txt holds your data)
Few points that you need to take from the code:
@ do not name you data structure variable 'dict'
@ use 'with' when you open files
@ work with defaultdict when you can
from collections import defaultdict
data = defaultdict(int)
with open('zz.txt') as f:
lines = [l.strip() for l in f.readlines()]
for line in lines:
fields = line.split(' ')
data[fields[0]] += int(fields[1])
print(data)
output
defaultdict(<class 'int'>, {'essi': 8, 'pietari': 26, 'aps': 25})
