I'm trying to output the values of 2 lists side by side using list comprehension. I have an example below that shows what I'm trying to accomplish. Is this possible?
code:
#example lists, the real lists will either have less or more values
a = ['a', 'b', 'c,']
b = ['1', '0', '0']
str = ['``` \n'
'results: \n\n'
'options votes \n'
#this line is the part I need help with: list comprehension for the 2 lists to output the values as shown below
'```']
print[str]
#what I want it to look like:
'''
results:
options votes
a 1
b 0
c 0
'''

You can use the zip[] function to join lists together.
a = ['a', 'b', 'c']
b = ['1', '0', '0']
res = "\n".join["{} {}".format[x, y] for x, y in zip[a, b]]
The zip[] function will iterate tuples with the corresponding elements from each of the lists, which you can then format as Michael Butscher suggested in the comments.
Finally, just join[] them together with newlines and you have the string you want.
print[res]
a 1
b 0
c 0

This works:
a = ['a', 'b', 'c']
b = ['1', '0', '0']
print["options votes"]
for i in range[len[a]]:
print[a[i] + '\t ' + b[i]]
Outputs:
options votes
a 1
b 0
c 0

from __future__ import print_function # if using Python 2
a = ['a', 'b', 'c']
b = ['1', '0', '0']
print["""results:
options\tvotes"""]
for x, y in zip[a, b]:
print[x, y, sep='\t\t']

[print[x,y] for x,y in zip[list1, list2]]
Note the square brackets enclosing the print statement.

Project description
Print two outputs side-by-side, in Python
side_by_side allows users to print two multi-line outputs side-by-side. This produces an effect similar to running diff -y file1 file2 in a Unix system.
Usage
This library provides a single function, side_by_side.print_side_by_side. To print two_strings side-by-side with default settings:
from side_by_side import print_side_by_side
print_side_by_side[s1, s2]
Optional parameters
print_line_numbers [bool]: If True, prints line-numbers along the left column.col_padding [int]: the number of spaces to leave between the two columns [and between the text and line number, if applicable]delimiter [str]: a delimiter to separate the columns
Fancy usage
Here's an example of a print format that uses all of the parameters:
from side_by_side import print_side_by_side
print_side_by_side[lorem_ipsum, lorem_ipsum, print_line_numbers=True, col_padding=24, delimiter='|++++|']
