 ```python
 my_dictionary = {

+In this code, `'A'` is the key and `1` is the value:
 
 ```python
-"A": 1
+'A': 1
 ```
 
 Alternatively, you can use `dict()`:
 
 ```python
-my_dictionary = dict(A="1", B="2", C="3")
+my_dictionary = dict(A=1, B=2, C=3)
 ```
 
 You can get the value through its corresponding key:
 
 ```python
-my_dictionary["A"]  # 1
+my_dictionary['A']  # 1
 ```
 
 You can also update the value associated with a key:
 
 ```python
-my_dictionary["A"] = 4
+my_dictionary['A'] = 4
 ```
 
 And you can remove a key-value pair:
 
 ```python
-del my_dictionary["A"]  
+del my_dictionary['A']  
 ```
 
 You can also check if a key is in the dictionary (or not):
 
 ```python
-"C" in my_dictionary
+'C' in my_dictionary
 ```
 
 And you can call these methods to get the keys, values, and items of the dictionary, respectively.
