Merge Numpy Array To Single Int

How can a numpy array like this: [10, 22, 37, 45] be converted to a single int32 number like this: 10223745

Solution 1:

This could work:

>>> int(''.join(map(str, [10, 22, 37, 45])))
10223745

Basically you use map(str, ...) to convert that array of integers to string, then ''.join to concatenate each of those strings, and finally int to convert the whole thing to an integer.
