[FIXED] how do you convert a list into a int in python in one/two lines?

Issue

If you want to convert a list into a int

You could use

x = ""
the_list = [5,7,8,6]
for integer in the_list:
       x+=str(integer)
ans = int(x)
#output
5786

is there a shorter way for doing this? Thanks for helping

Solution

str has a join method, where it takes a list as an argument and joins each element by given string.

For example you can create a comma separated line as such:

the_list = ["foo", "bar"]
print(",".join(the_list))

result:

foo,bar

Remember, all elements of the list must be strings. So you should map it first:

the_list = [1, 2, 3, 4]
print(int("".join(map(str, the_list))))

result:

1234
