Python Program To Convert An Array List Into A String And Viceversa
Python is a powerful programming language that is versatile and easy to understand. It is commonly used for web development, data analysis, artificial intelligence, and more. In this article, we will look at how to convert an array into a string and vice versa in Python.
Converting an array to a string
The first step to converting an array to a string is to have an array to work with. We can create an array by using square brackets and separating the elements with commas. Here’s an example:
my_array = ['apple', 'banana', 'cherry', 'date']
Now, to convert this array into a string, we can use the built-in function join()
. This function takes an iterable (like a list or a tuple) and joins its elements into a single string using a separator. Here’s an example:
my_string = ', '.join(my_array)
print(my_string)
The output of this code will be:
apple, banana, cherry, date
As you can see, the join()
function has joined the elements of the my_array
array into a single string separated by commas.
Converting a string to an array
Now that we know how to convert an array to a string, let’s look at how to convert a string to an array. This can be done by splitting the string into its individual elements using a separator.
Here’s an example:
my_string = 'apple,banana,cherry,date'
my_array = my_string.split(',')
print(my_array)
The output of this code will be:
['apple', 'banana', 'cherry', 'date']
As you can see, the split()
function has split the my_string
string into its individual elements based on the comma separator and stored them as elements within the my_array
array.
Conclusion
In conclusion, converting an array to a string or vice versa is a common task in programming. Fortunately, Python makes this task easy with built-in functions like join()
and split()
. With this knowledge, you can easily convert arrays and strings in your Python programs.
