How can I take text file and access/return a specific line from the file? For example, "File.txt" is 100 lines long and I want the information that's contained on lines 1,31,61 and 91.
dataFile = open("File.text","a+")

Do you want something like this?
def get_lines(filename, line_numbers):
with open(filename) as f:
for line_number, line in enumerate(f):
if line_number in line_numbers:
yield line_number, line
for line_number, line in get_lines('tmp.txt', (1, 3)):
print(line_number, line)
This code returns a generator iterator so you should loop through it.
