Define the draw_histogram() function which is passed a Python dictionary as a parameter. The keys of the dictionary are single letters and the corresponding values are integers, e.g., {'b': 5, 'a': 6, 'c': 3}. For each key:value pair in the dictionary the function prints the key, followed by ": ", followed by a series of stars. The number of stars printed is given by the value corresponding to the key. The keys are printed in alphabetical order. Note that the key is not printed if the corresponding value is a number less than 1.

For example, the following code:

print("1.")
draw_histogram({'a': 2, 'c': 7, 'b': 5})
print()

print("2.")
draw_histogram({'a': 0, 'c': 5, 'b': 7, 'f': 0})

prints the following:

1.
a: **
b: *****
c: *******

2.
b: *******
c: *****

Answer 1

def draw_histogram(d):
    for k in sorted(d.keys()):
        if d[k] > 0:
            print(k + ": " + ("*" * d[k]))


print("1.")
draw_histogram({'a': 2, 'c': 7, 'b': 5})
print()
print("2.")
draw_histogram({'a': 0, 'c': 5, 'b': 7, 'f': 0})
