Updated README Usage to work with function argument

[rudSarkar]

This PR is about a few changes on the README file, where I added demo usages because people mostly find and wanted to work with function arguments instantly. I created this PR because there are more lazy people like me who will find it useful.

Another example given below is to work with multiple arguments.

import schedule
import time

def job():
    print("I'm working...")

""" working with multiple argument """
def function_job(name, age):
    print(f"I am {name} and my age is: {age}")

schedule.every(10).seconds.do(job)
schedule.every(10).seconds.do(function_job, name="Peter Griffin", age=22)
    
while True:
    schedule.run_pending()
    time.sleep(1)

Thanks,
@rudSarkar

Looks good! I like that this makes it easier for people to get started.

Just a few small suggestions to tidy it up.

[SijmenHuizenga]

Suggested change

	schedule.every(10).seconds.do(job, name="Peter Griffin")
	schedule.every(10).seconds.do(job, name="Peter")

Let's keep the readme clean of cultural references 😄

Sure thing

@SijmenHuizenga sorry for this but the function name here need to be changed schedule.every(10).seconds.do(job, name="Peter") to schedule.every(10).seconds.do(function_job, name="Peter")
