Let us say, we have a Dictionary that contains,
As 'Key' and 'Value' pair.
Now, let us say, we want to update the value of the 'Key', '5' with 'Is an one digit number'.
5, Is an one digit number
Where '5' is the 'Key' and 'Is an one digit number' is the new 'Value'.
We can update the entries of a Dictionary using two ways :
Let us see in the below example using the first way.
x = {
5 : "Is a Number",
"John": "Is a Name",
"Python": "Is a Language"
}
x[5] = "Is an one digit number"
print(x)
So, in the above code we have created a 'Dictionary' using braces '{ }' and 'Key' and 'Value' pairs.
x = {
5 : "Is a Number",
"John": "Is a Name",
"Python": "Is a Language"
}
And initialised to the variable 'x'.
Now, we are supposed to update the value of the 'Key', '5' with 'Is an one digit number'.
So, we have used the below way to update it.
And the entry for the 'Key' '5' is updated in the 'Dictionary'.
And we get the below output,
Let us see the second way of updating the 'Key' 'Value' using the 'update( )' Function.
x = {
5 : "Is a Number",
"John": "Is a Name",
"Python": "Is a Language"
}
x.update({5: "Is an one digit number"})
print(x)
So, in the above code we have created a 'Dictionary' using braces '{ }' and 'Key' and 'Value' pairs.
x = {
5 : "Is a Number",
"John": "Is a Name",
"Python": "Is a Language"
}
And initialised to the variable 'x'.
Now, we are supposed to update the value of the 'Key', '5' with 'Is an one digit number'.
So, we have used the below way to update it.
And the entry for the 'Key' '5' is updated in the 'Dictionary'.
And we get the below output,
