Cheatsheet Of Python



The.count Python list method searches a list for whatever search term it receives as an argument, then returns the number of matching entries found. Backpack = 'pencil', 'pen', 'notebook', 'textbook', 'pen', 'highlighter', 'pen' numPen = backpack.count('pen') print (numPen) # Output: 3. Python provides a.get method to access a dictionary value if it exists. This method takes the key as the first argument and an optional default value as the second argument, and it returns the value for the specified key if key is in the dictionary. If the second argument is not specified and key is not found then None is returned.
