python – Why multiple defines gives IndentationError

I’ve made an script and want to import it to another script but I get IndentationError on the first script. Please share your solution. Thanks. My first script codes are as follows:

Code:

from requests import get
def service(phone):
def support(phone):
def arkline(phone):

The error:

File "/home/linux/0/Api.py", line 3
    def support(phone):
    ^
IndentationError: expected an indented block
