So in order to achieve a desired output, we should first know how the function works.
The syntax for join() method as described in the python documentation is as follows:
string_name.join(iterable)
Things to be noted:
string concatenated with the elements of iterable. The separator between the elements being the string_name. iterable will raise a TypeErrorNow, to add white spaces, we just need to replace the string_name with a " " or a ' ' both of them will work and place the iterable that we want to concatenate.
So, our function will look something like this:
' '.join(my_list)
But, what if we want to add a particular number of white spaces in between our elements in the iterable ?
We need to add this:
str(number*" ").join(iterable)
here, the number will be a user input.
So, for example if number=4.
Then, the output of str(4*" ").join(my_list) will be how are you, so in between every word there are 4 white spaces.
