如何使用ints输出python连接ints列表

Question

i have list of integers, how this list join to get output with the same list but joined every three value.

lst = [22, 33, 44, 11,33,11]

how to get

lstOutput = [223344, 113311]

with string everything clear, i try:

[lst[i:i + 3] for i in range(0, len(b), lst)]

Sorry for english

Answer 1

you can use map(str,lst[i:i+3]) to convert your int element to string then join them with join function :

>>> [''.join(map(str,lst[i:i+3])) for i in range(0,len(lst),3)]
['223344', '113311']

and if you want the int value use this :

>>> l=[lst[i:i+3] for i in range(0,len(lst),3)]
>>> [sum(j*(100**i) for i,j in enumerate(i[::-1])) for i in l]
[223344, 113311]

as l is equal [[22, 33, 44], [11, 33, 11]] and you need to multiple the element with 100 to power of index you need to reverse the split list by [::-1] and convert every list to its reverse like [44, 33, 22] and then add them.
