Answer:
- To get the items of a dictionary and print them as a string, use the items() method to unpack the keys and values in a for and print or write them into a file.
for key, value in mydict.items():
print(f"{key}, {value}")
- To convert string from user input into dictionary;
mystring = input().split(" ") #assuming the words are separated by a space.
from word in mystring:
mydict[word] = mydict.get(word, 0) + 1
This would use the words in the string as the keys of the dictionary and the count of each word as the respective values.
Explanation:
A dictionary is a data structure in python used to store data in key-value pairs. The items are enclosed in curly braces and can be accessed with the key in dot or bracket notation.
