In two previous chapters, we considered methods that split a string into a list. Now we will learn the method that will do the opposite thing.

To join all the elements of iterable object `obj` (like tuple, list, dictionary or set) use the following syntax: `separator.join(obj)`, where `separator` is the string used to separate objects for join. If `obj` is dictionary, then its keys will be joined. For example,

print(", ".join(['Python', 'R', 'SQL']))
print(" - ".join(('1', '2', '3')))

As a data scientist or analyst, you will have to deal with different data types. The first thing that comes to mind - is numerical data, of course. But also you will have to deal with textual data often. In this course, you will dive into strings, that represent textual data in Python, and learn how to perform different manipulations with them.

In this section you will be introduced with the basic concepts of strings in Python, such as creating, indexing, and slicing.

In this section we will learn important strings methods, like .split, .count, .strip and so on...

In this section we will learn how to format strings, learn about f-string conception, replacing particular parts of strings, splitting string by lines and so on...
