I have a list like this:
my_list = ['Normal adult dogs have how many teeth?\n', '64#32#42#16\n', '42\n', '10\n', '20\n', 'What is the most common training command taught to dogs?\n',
'Sit#Beg#Shake#Catch\n', 'Sit\n', '10\n', '20\n', 'What is this?;{;i1.png;};\n', 'Lion#Dog#Cat#Puppy\n', 'Puppy\n', '10\n', '20', 'Which part of cats is as unique as human fingerprints?\n', 'Paw Prints#Nose Prints#Stripes Color#Eye Colors\n', 'Nose Prints\n', '10\n', '20\n', 'What is a group of
cats called??\n', 'Clowder#Herd#Pack#Flock\n', 'Clowder\n', '10\n', '20\n', 'What is this?;{;i1.png;};\n', 'Lion#Dog#Cat#Puppy\n', 'Cat\n', '10\n',
'20']
The above list will always follow a specific pattern like this :
1st element = A question
2nd element = Options for questions
3rd element = correct answer
4th element = marks from question
5th element = Time alloted
I want to make 5 different lists from the above list with all Questions in 1st list, all options in 2nd list, all correct answer in 3rd list, Marks for each question in one list and Time alloted in 5th list.
Is there a way i can do it?
desired output=
ques = [my_list[0],my_list[5],my_list[10]....]
options = [my_list[1],my_list[6],my_list[11]....]
correct_answer = [my_list[2],my_list[7],my_list[12]....]
Marks = [my_list[3],my_list[8],my_list[13]....]
Time = [my_list[4],my_list[9],my_list[14]....]
I tried to solve it by using the following code:
for i in range(0,len(my_list)):
ques = my_list[i]
options = my_list[i+1]
correct_answer = my_list[i+2]
Marks = my_list[i+3]
Time = my_list[i+4]
i+5
But it throws following error:
Time = my_list[i+4]
IndexError: list index out of range
>Solution :
There are a few adjustment you need to make:
- don’t increase
imanually in the loop but use step value inrange(start, end, step). The step value here would need to be 5. - You need to append the results to the list, otherwise you are just replacing the value over and over again and only the last value will be stored in the variables at the end of the
for loop. - you probably want to strip the newlines
\n(but this is optional) usingrstrip("\n"). - you probably also want to have all the possibilities for an answer in an array (but this is also optional). You can do that by using
split("#")on the relevant string.
