Question

I would like to either extend or append a list to the content of another list:
I’ve got the following:

l = (('AA', 1.11,'DD',1.2), ('BB', 2.22, 'EE', 2.3), ('CC', 3.33, 'FF', 3.45))
ls = [('XX', 7.77), ('YY', 8.88), ('ZZ', 9.99)]
m = ['first', 'second', 'third']
for i in range(len(l)):
    result = []
    for n in m:
        if n == "first":
            r=[]
            for word, number in ls[i]:
                temp = [word, number]
                r.append(temp)
            for t in r:
                result.extend(t)
            print result

I would like to see the following result when the ‘result’ is printed out in the above code (each in newline):

['AA', 1.11, 'XX', 7.77]
['BB', 2.22, 'YY', 8.88]
['CC', 3.33, 'ZZ', 9.99]

Many thanks in advance.

Answer 1

All you need is zip:

l = (('AA', 1.11), ('BB', 2.22), ('CC', 3.33))
ls = [('XX', 7.77), ('YY', 8.88), ('ZZ', 9.99)]

for x,y in zip(l,ls):
    print(list(x+y))

# ['AA', 1.1100000000000001, 'XX', 7.7699999999999996]
# ['BB', 2.2200000000000002, 'YY', 8.8800000000000008]
# ['CC', 3.3300000000000001, 'ZZ', 9.9900000000000002]
