how to sort using 3 parallel array lists:
num1 = ['a','b','c,']
num2 = ['apple','pear','grapes']
num3 = [2.5,4.0,.68]
I used 2 for statements followed by a if statement. Sorting by elements the output should be:
a apple 2.5
b pear 4.0
c grapes .68
unfortunately, I am having issues with sorting the 3rd num3 values using the element swapping sort. any ideas
Since you say the lists are parallel, let's group them into tuples, and then sort the list of tuples.
num1 = ['a','b','c']
num2 = ['apple','pear','grapes']
num3 = [2.5,4.0,.68]
lst = zip(num1, num2, num3)
lst.sort()
for x1, x2, x3 in lst:
print x1, x2, x3,
print
The result is:
a apple 2.5 b pear 4.0 c grapes 0.68
From your desired inputs and output it doesn't seem you want any sorting -- just:
num1 = ['a','b','c']
num2 = ['apple','pear','grapes']
num3 = [2.5,4.0,.68]
for item in [x for t in zip(num1, num2, num3) for x in t]:
print item,
print
This does give the output you mention -- is this what you want?
