Merge List To String In Python
You can merge the elements of a list into a string with a given separator. This is done using the join method. The method is applied to the string that will act as a separator, and the method parameter specifies the list to be merged:
lst = ['1', '2', '3']
res = '/'.join(lst)
print(res) # '1/2/3'
An important nuance of the join method is that we can only merge lists with string elements. Otherwise, we will get an error:
lst = [1, 2, 3]
res = '/'.join(lst)
print(res) # will display an error
Given a list:
lst = ['a', 'b', 'c', 'd', 'e']
Merge this list into a string using the separator '-'.
The following code is given:
lst = ['a', '1', 'b', '2']
res = ''.join(lst)
print(res)
Tell me what will be output to the console.
The following code is given:
lst = ['1', '2', 3, '4']
res = '/'.join(lst)
print(res)
Tell me what will be output to the console.
Given a list:
lst = ['4', '3', '2', '1']
Write the code to get the following string:
