You can't, but if you want to put 0's (zero padding) at the beginning of your number, this is the way to do it.

"{:04}".format(123)
# '0123'

"{:05}".format(123)
# '00123'

@SheikhJames As everyone here pointed out, it's not possible. You need to change your way of thinking or the implementation. – BcK May 09 '18 at 08:49

Like every one said you can try above answers or the following :

string_value = '0123'
int_no = int(string_value)

print("%04d" % int_no)

print(string_value.zfill(4))

Both will give same answer

Impossible, you cannot get an integer value of 0123.

You should change your mind, you do not actually need 0123 in integer, but you need to keep zero when displaying it. So the question should change to how to format output.
