Given a dictionary myDictionary
, write a function that prints all of the key/value pairs of the dictionary, one per line, in the following format:
key: value
key: value
key: value
Use the following function header:
def printKeyValuePairs(myDictionary):
For example, if
myDictionary = {'The Beatles':10, 'Bob Dylan':10, 'Radiohead':5}
your function would print
The Beatles: 10
Bob Dylan: 10
Radiohead: 5
for key in myDictionary:
print("{}: {}".format(key, myDictionary[key]))
I read on SO somewhere there is a good reason not to either access dictionary values using myDictionary[key]
over the following, or visa-versa, but I can't recall where (or if I'm remembering correctly).
for key, value in myDictionary.items():
print(f"{key}: {value}")
There are essentially two (modern) ways to do string formatting in Python, both covered in great detail [here][1]:
"var1: {}, var2: {}".format("VAR1", "VAR2")
f"var1: {"VAR1"}, var2: {"VAR2"}"
Both yield var1: var1, var2:VAR2
, but the latter is only supported in Python 3.6+.
here is a simple function that prints all the key value pairs in a dictionary:
def printKeyValuePairs(myDictionary):
"""prints each key, value pair in a line"""
for key, val in myDictionary.items():
print("{}: {}".format(key, val))
if the a dictionary has the following key, value pairs:
my_dict = {'The Beatles':10, 'Bob Dylan':10, 'Radiohead':5}
if we call the function defined above, we get the following output:
printKeyValuePairs(my_dict)
The Beatles: 10
Bob Dylan: 10
Radiohead: 5
