In the example above, we have ommited the start, stop arguments, because we require all elements in the tuple and passed step as -1, so it creates a new tuple by beginning with the end element of a tuple goes all the way to first element. Conclusion In this article, I have shared ...
What is the best way to sum all values in a pandas dataframe? How to access the last element in a pandas series? ImportError: No module named 'xlrd' Adding dummy columns to the original dataframe How to reset index pandas dataframe after dropna() pandas dataframe?
Tuple = ("a", "b", "c") for x in Tuple: print(x) 4. Check if an item exist in tuple To check if a tuple contains a given element, we can use 'in' keyword and 'not in' keywords. Tuple = ("a", "b", "c", "d", "e", "f") if "a" in Tuple: print("Yes, 'a...
I executed the above Python code, and you can see the output in the screenshot below: Check outSort a List of Tuples by the First Element in Python 2. Using the += Operator to Concatenate Tuples Another way to concatenate tuples is by using the+=operator in Python. This operator allo...
You should use .items() to access key-value pairs when iterating through a Python dictionary. The fastest way to access both keys and values when you iterate over a dictionary in Python is to use .items() with tuple unpacking.To get the most out of this tutorial, you should have a ba...
5. What is the difference between split() and list() in Python? split() divides a string by a delimiter, while list() converts each string character into a separate list element. For example: # Using split() string = "apple,banana,cherry" list_of_fruits = string.split(",") print(...
Python has an in-built function called open() to open a file. It takes a minimum of one argument as mentioned in the below syntax. The open method returns a file object which is used to access the write, read and other in-built methods. ...
The example above defines a tuple my_tuple with elements 1, 2, ‘a’, ‘b’, True, and. We can access individual elements of the tuple using indexing, just like lists. However, if we try to change an element of the tuple, it will return an error because tuples are immutable. Usual...
Now what if we desired a function that computed both squares and cubes and returned them both? How can we do that? A Python function can only return one object, not two. The solution is to package the square and cube into a single tuple and return the tuple. ...
