Python Program to Create a Dictionary with Key as First Character and Value as Words Starting with that Character
When it is required to create a dictionary with the key as the first character and the associated value as the word which is the starting of that character, the s’plit’ method, a dictionary and simple ‘if’ condition is used.
Example
Below is a demonstration for the same −
my_string=input("Enter the string :")
split_string = my_string.split()
my_dict={}
for elem in split_string:
if(elem[0] not in my_dict.keys()):
my_dict[elem[0]]=[]
my_dict[elem[0]].append(elem)
else:
if(elem not in my_dict[elem[0]]):
my_dict[elem[0]].append(elem)
print("The dictionary created is")
for k,v in my_dict.items():
print(k,":",v)Output
Enter the string :Hey Jane, how are you The dictionary created is H : ['Hey'] J : ['Jane,'] h : ['how'] a : ['are'] y : ['you']
Explanation
- The string is taken as input from the user.
- This is assigned to a variable.
- This string is split, and assigned to a variable.
- An empty dictionary is created.
- The variable is iterated over, and if the first element is not present as a key in the dictionary, its element is assigned an empty list.
- Now, the elment is added to the dictionary.
- Otherwise, the element is directly appended to the dictionary.
- This dictionary is created, and is displayed on the console.
