Python program to create a dictionary with integer keys, and print the keys, values & key-value pairs

A dictionary contains the pair of the keys & values (represents key : value), a dictionary is created by providing the elements within the curly braces ({}), separated by the commas.

Here, we are creating a dictionary with integer keys and printing the dictionary, it’s keys, it’s values and key-value pairs.

Printing the dictionary – To print a dictionary, just pass the dictionary_name in the print function.
Syntax:
```
print(dictionary_name)
```
Printing the keys – To print the dictionary keys only, loop through the dictionary and print it, when we loop through a dictionary it returns the keys.
Syntax:
```
for key in dictionary_name:
    print(key)
```
Printing the values – To print the dictionary values only, loop through the dictionary and use the values() method, it returns the dictionary values.
Syntax:
```
for value in dictionary_name.values():
    print(value)
```
Print the key-value pairs – To print the keys & values both, loop through the dictionary and use the items() method, it returns the key-value pair.
Syntax:
```
for key,value in dictionary_name.items():
    print(key, value)
```
