Python dict() Function with Examples

dict() Function in Python:

The dict() function is used to create a dictionary.

A dictionary is an unordered, changeable, and indexed collection.

Syntax:

dict(keyword arguments)

Parameters

keyword arguments: This is Required. You can use as many keyword arguments as you want, separated by a comma: key = value, key = value…

Return Value:

dict() does not return any results (returns None).

Examples:

Example1:

Input:

Given key-value pairs = (emp_name="sunny", emp_id=2122, jobrole="software developer")

Output:

The result dictionary is :
{'emp_name': 'sunny', 'emp_id': 2122, 'jobrole': 'software developer'}

Example2:

Input:

Given key-value pairs = (one="hello", two="good", three="morning")

Output:

The result dictionary is :
{'one': 'hello', 'two': 'good', 'three': 'morning'}

Method #1: Using Built-in Functions (Static Input)

Approach:

Pass some random key-value pairs as the arguments to the dict() function and store it in a variable.
Print the above result.
The Exit of the Program.

Below is the implementation:

# Pass some random key-value pairs as the arguments to the dict() function
# and store it in a variable.
rslt = dict(emp_name="sunny", emp_id=2122,  jobrole="software developer")
# Print the above result
print("The result dictionary is :")
print(rslt)

Output:

The result dictionary is :
{'emp_name': 'sunny', 'emp_id': 2122, 'jobrole': 'software developer'}

Method #2: Using Built-in Functions (User Input)

Approach:

Take a dictionary and initialize it with an empty dictionary using dict() or {}.
Give the number of keys as user input using int(input()) and store it in a variable.
Loop till the given number of keys using for loop.
Inside the for loop scan the key and value as user input using input(), split() functions, and store them in two separate variables.
Initialize the key with the value of the dictionary.
Print the above-given dictionary.
The Exit of the Program.

Below is the implementation:

# Take a dictionary and initialize it with an empty dictionary using dict() or {}.
gvn_dict = dict()
# Give the number of keys as user input using int(input()) and store it in a variable.
numb_of_kys = int(
    input('Enter some random number of keys of the dictionary = '))
# Loop till the given number of keys using for loop.
for p in range(numb_of_kys):
        # Inside the for loop scan the key and value as
    # user input using input(),split() functions
    # and store them in two separate variables.
    keyy, valuee = input(
        'Enter key and value separated by spaces = ').split()
    # Initialize the key with the value of the dictionary.
    gvn_dict[keyy] = valuee
print("The result dictionary is :")
print(gvn_dict)

Output:

Enter some random number of keys of the dictionary = 3
Enter key and value separated by spaces = one hello
Enter key and value separated by spaces = two good
Enter key and value separated by spaces = three morning
The result dictionary is :
{'one': 'hello', 'two': 'good', 'three': 'morning'}
