How do you join two lists in Python?
Join Two ListsJoin two list: list1 = [“a”, “b” , “c”] list2 = [1, 2, 3] list3 = list1 + list2. print(list3) … Append list2 into list1: list1 = [“a”, “b” , “c”] list2 = [1, 2, 3] for x in list2: list1.append(x) … Use the extend() method to add list2 at the end of list1: list1 = [“a”, “b” , “c”] list2 = [1, 2, 3] list1.extend(list2)
What is a python iterable?
Definition: An iterable is any Python object capable of returning its members one at a time, permitting it to be iterated over in a for-loop. Familiar examples of iterables include lists, tuples, and strings – any such sequence can be iterated over in a for-loop.
What is slicing in Python?
Slicing in python means taking elements from one given index to another given index. We pass slice instead of index like this: [start:end] . We can also define the step, like this: [start:end:step] . If we don’t pass start its considered 0. If we don’t pass end its considered length of array in that dimension.
How do you join DataFrames in Python?
To join these DataFrames, pandas provides multiple functions like concat() , merge() , join() , etc. In this section, you will practice using merge() function of pandas. You can notice that the DataFrames are now merged into a single DataFrame based on the common values present in the id column of both the DataFrames.
What are tuples in Python?

How do you use the map function in Python?
The map() function applies a given to function to each item of an iterable and returns a list of the results. The returned value from map() (map object) can then be passed to functions like list() (to create a list), set() (to create a set) and so on.

Can only join an iterable Python?
The “TypeError: can only join an iterable” error is caused when you try to join a value that is not iterable to a string. This can happen if you assign the value of a built-in list method such as sort() to a new variable and try to join the result of that operation to a string.
