This function might be helpful when you are calling a tuple somewhere in your program and you want to make sure that the tuple is populated. tuple() Use tuple() to converts a data type to tuple. For example, in the code chunk below, you convert a Python list to a tuple. a_list ...
used to return multiple values from a function. Keys in dictionaries: Tuples can be used as keys in dictionaries because they are immutable. Conclusion In conclusion, Tuples in python are helpful for maintaining consistent data and especially when we want to work with immutable data. Also Read:...
To determine how many items a tuple has, use thelen()function: Example Print the number of items in the tuple: thistuple = ("apple","banana","cherry") print(len(thistuple)) Try it Yourself » Create Tuple With One Item To create a tuple with only one item, you have to add a ...
/usr/bin/python3 tup1 = (12, 34.56) tup2 = ('abc', 'xyz') # Following action is not valid for tuples # tup1[0] = 100; # So let's create a new tuple as follows tup3 = tup1 + tup2 print (tup3) When the above code is executed, it produces the following result −...
4. Using the itertools.chain() Function If you have multiple tuples that you want to concatenate, you can use theitertools.chain()function in Python from theitertoolsmodule. This function takes multiple iterables as arguments and returns a single iterable that combines all the elements. ...
thistuple = ("apple", "banana", "cherry") for i in range(len(thistuple)): print(thistuple[i]) Try it Yourself » Using a While LoopYou can loop through the tuple items by using a while loop.Use the len() function to determine the length of the tuple, then start at 0 and...
In this case, you can return the empty tuple to keep your function consistent regarding its return type.You’ll find a couple of other situations where using the parentheses is required. For example, you need it when you’re interpolating values in a string using the % operator:...
in code, but the underlying object doesn't actually change. You're simply reassigning the variable name to another object. Tuples are great if you have multiple return values from a function; you can return them all as a tuple, then 'unpack' them in the calling function to whatever ...
Tuples have many uses in Python programming. 一个特别重要的用例是当您希望从Python函数返回多个对象时。 One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that...
