Most arguments are identified by their position in the function call.

random.randint(1, 10)
# random.randint(10, 1) causes an error. 
# Order of arguments matters

Keyword arguments are identified by the keyword put before them in the function call. Keyword arguments are often optional parameters.

See:

• parameters
• arguments

Example:

print('Hello', end='')
print('World')

Output:

HelloWorld

Example:

>>> print('cats', 'dogs', 'mice')
cats dogs mice
>>> print('cats', 'dogs', 'mice', sep=',')
cats,dogs,mice

Note how the print() function automatically separates strings with a ' ‘, but you can specify the field separator with sep=.
