Question

'''
string_funcs
==========
Complete the following functions. You MUST, MUST, MUST add:

1) a doc comment in the proper location for EACH function that describes
the basic purpose of the function.
2) AT LEAST 3 doc test comments in EACH function that:
* test that the function does what it is supposed to do
* tests that it does what it's supposed to do with odd inputs
* tests "edge" cases (numbers at, just above, just below min/max, empty strings, etc.)

You MUST, MUST, MUST then test each of your methods by BOTH:

1) running the "main.py" script
2) running this module directly to run the doc tests

Except as noted, you can implement the functions however you like. You can use string
functions OR f-strings to accomplish the formatting.

CHALLENGE: Use try/except blocks to avoid crashes when passing in unexpected parameters.

IMPORTANT!!! MIMIR RUNS PYTHON 3.5 WHEN YOU RUN python3. F-STRINGS ARE NEW TO PYTHON
3.6 AND ABOVE. IF TESTING ON MIMIR, YOU MUST RUN python3.6 INSTEAD OF JUST python3
IF YOU USE F-STRINGS.

print_header
------------
Print out a header line that prints the "text" parameter such that it is centered and
takes up a total of 60 characters. It should then print a second line that contains
60 "+" symbols. In other words, calling:

print_header('2021 Crop Report')

should print as follows:

2021 Crop Report
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

print_integer_line
------------------
Print out a line of text where the "text" parameter is left aligned and takes up
a total of 50 characters and the "value" parameter is right aligned and takes up
10 characters. In other words, calling:

print_integer_line('Fall 2020 Enrollment',504)

should result in a printed line as follows:

Fall 2020 Enrollment 504

print_float_line
----------------
Print out a line of text where the "text" parameter is left aligned and takes up
a total of 45 characters and the "value" parameter is right aligned and takes up
15 characters AND is displayed as a float value with TWO decimal place. So, calling:

print_float_line('The value of e',2.718281828459045)

will print as follows:

The value of e 2.72

print_footer
------------
Print out a footer line that prints a single line of 60 "+" characters followed
by a line that prints the "left", "middle" and "right" parameters such that left
is aligned to the left, middle is centered, and right is aligned to the right.
Each should take up 20 characters. In other words, if I call:

print_footer('1/1/2020','Summary Data','page 1 of 1')

your printed output should be:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1/1/2020 Summary Data page 1 of 1

print_circle_area
-----------------
Finally, print out the surface are of a circle using your print_float_line function AND
using your circle_area function from math_funcs. You will thus need to import the
required function from math_funcs (remember that this is in the "funcs" directory, so
you need to be sure to import it correctly). Call your print_float_line function with the
results and appropriate description. For example, calling:

print_circle_area(5)

should result in a printed line as follows:

The area of a circle with radius of 5 78.54
