How to replace values of a Python dictionary?

You can assign a dictionary value to a variable in Python using the access operator []. For example,

Example

my_dict = {
   'foo': 42,
   'bar': 12.5
}
new_var = my_dict['foo']
print(new_var)

Output

This will give the output −

42

This syntax can also be used to reassign the value associated with this key. For example,

Example

my_dict  =  {
   'foo': 42,
   'bar': 12.5
}
my_dict['foo']  =  "Hello"
print(my_dict['foo'])

Output

This will give the output −

Hello
