Question

My code doesnt pass this test case

How would I get my code to pass this test case?

Sample Input 3

this file, tests TEST a, b c erroneous cases TEST, a, b there should, only, be TEST, a b six lines, in, the, output TEST a b and it, should TEST a , b, c include this, one TEST a, b,, c

Sample Output 3

this file tests erroneous cases there should only be six lines in the output and it should include this one

Explanation 3

All of the lines beginning with TEST have some sort of syntax error, so they should be omitted from the output. The other lines have no errors, so they should be tokenized and output. The errors are as follows:

TEST a, b c: the comma between b and c is missing

TEST, a, b: there is an extra comma after TEST

TEST, a b: the comma between a and b is missing, and there is an extra comma after TEST

TEST a b: the comma between a and b is missing

TEST a , b, c: there is a space before the comma between a and b

def tokenize(line):
token_list = []
for token in line.split():
token_list.extend(token.strip(",").split(","))
return token_list

def main():
line_list = []

while True:
try:
line = input().strip()
if not line:
break
line_list.append(line)
except EOFError:
break

for line in line_list:
tokenized_line = tokenize(line)
if any("," in token for token in tokenized_line):
continue
print(" ".join(tokenized_line))

if __name__ == "__main__":
main()
