Say I have some lists:
t = ['a','b']
x = ['x1','x2','x3','x4']
y = ['y1','y2','y3','y4']
I would like to combine elements from those lists above, so I would have a new list looks like this
new = ['ax1y1x2y2','bx3y3x4y4']
How do I do this in Python?
So your question is a bit vague which makes it hard for me to know exactly what you are looking for. But in general you can access the specific element n from a Python list foo with the code foo[n]. Therefore you can build a general list bar of length l where you also have lists ham, eggs and spam with something like:
bar = list()
for i in range(l):
bar.append(str(ham[i]) + str(eggs[i]) + str(spam[i//2]))
Where of course you can access whatever elements of ham, eggs, and spam are best for your purposes.
As a side note, the people in the comments on your post asking you to edit your string format mean that they want your code to be in the form:
t = ['a','b']
As opposed to:
y = ['y1,'y2','y3',y4']
Notice how the single quote ' to the right of y1 and to the left of y4 is missing in the text for y.

I'm not quite sure if this is what you wanted, but I made a function that does what you described. There are many ways to make it more efficient, but I'll leave that up to you.
t = ['a','b']
x = ['x1','x2','x3','x4']
y = ['y1','y2','y3','y4']
def big_zip(t,x,y):
a = zip(x, y)
b = []
new_list = []
final = []
for i in a:
b.append(i[0]+i[1])
for i in range(0,len(b)-1,2):
new_list.append(b[i]+b[i+1])
for i in range(0,len(t)):
final.append(t[i]+new_list[i])
return final
print(big_zip(t,x,y))
'y4'value didn't have the'. Eitherway, you need to always provide whatever you were able to accomplish. Even if it was a for loop that didn't work, any code of a previous attempt is useful for us to tell you what went wrong on your solution and help you improve in your code.
