Answer 1

You could also use the old kind of % formatting:

print "this is a test %03d which goes on" % 10

This page https://pyformat.info/ has quite a nice comparison !

Answer 2

With Python 3.6+ (PEP498), you can use formatted string literals, also known as f-strings:

amount1 = input('Insert your value: ')
amount2 = input('Insert your value: ')

print(f'Your first value is {amount1}, your second value is {amount2}')

Answer 3

Use string formatting:

s = "Your first value is {} your second value is {}".format(amount1, amount2)

This will automatically handle the data type conversion, so there is no need for str().

Consult the Python docs for detailed information:
