Combining digit in a list to make an integer

[Harlin Seritt]

I have the following:

num1 = ['1', '4', '5']

How can I combine the elements in num1 to produce an integer 145?

thanks,

int(''.join(num1))

If anyone has time, would you mind explaining the code that Dan Bishop
was so kind as to point out to me:

int(''.join(num1))

This worked perfectly for me, however, I'm not sure that I understand
it very well.

Thanks,

''.join(list of strings) is a python idiom for fast string
concatenation. ''.join(num1) would give "145". The function int() is
then used to convert the resulting string into an integer.

join(...)
S.join(sequence) -> string

Return a string which is the concatenation of the strings in the
sequence. The separator between elements is S.

For example:

'<'.join(['1', '2', '3'])

'1<2<3'

If you don't want a separator, simply let S be the empty string ('').

num1 = ['1', '4', '5']
