Enum string comparison To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Pyt...
12.find an item's offset by value with index() 13.To count how many times a particular value occurs in a list, use count(). 14. Convert a List to a String with join() Join() is a string method, not a list method.It might help to remember—join() is the opposite of split()...
Tuple unpacking iterates. Using * operator in a function call iterates (see Unpacking iterables into function arguments). Using * operator in a list literal iterates (see Unpacking iterables into iterables). Iterable (Our perspective as Python users) Anything you can loop over with a for ...
arr = [1, 2, 3, 4, 5, 6] # Create a list (not an array, but works similarly) total = 0 # Initialize a variable to hold the sum for element in arr: # Iterate over the array total += element # Add each element to the total print(total) # Output: 21 Copy 4. What is ...
The for loop is used to iterate over structures like lists, strings, etc. Strings are inherently iterable, which means that iteration over a string gives each character as output. For example, for i in "String": print(i) Output: S t r i n g In the above example, we can directly...
How to resolve the “List Index Out of Range” error inforloops Below are some ways to tackle theList Index Out of Rangeerror when working withforloops. Use enumerate() You can make use of theenumerate()function to iterate over both the indices and elements of the list simultaneously. This...
