String Split and Join

January 22, 2024

In Python, a string can be split on a delimiter.

Example:

>>> a = "this is a string"
>>> a = a.split(" ") # a is converted to a list of strings. 
>>> print a
['this', 'is', 'a', 'string']

Joining a string is simple:

>>> a = "-".join(a)
>>> print a
this-is-a-string 

Sample Input

this is a string   

Sample Output

this-is-a-string

def split_and_join(line):
    line = line.split(" ")
    line = "-".join(line)
    return line

if __name__ == '__main__':
    line = input()
    result = split_and_join(line)
    print(result)
