Detailed answer by teachoo
To find the output of the code, we need to understand how the string methods work in Python. The string methods are:
- split() : This method splits a string into a list of words based on a separator. If no separator is given, it splits on whitespace.
- join() : This method joins a list of strings into one string using a separator. The separator is a string that is placed between each element of the list.
- upper() : This method returns a copy of a string with all letters converted to uppercase.
- capitalize() : This method returns a copy of a string with only its first letter capitalized and the rest lowercase.
Evaluating the code step by step:
- s = “Python is fun”
First, we assign the string “Python is fun” to the variable s.
- l = s.split()
Next, we split s into a list of words using the split() method and assign it to the variable l. So, l becomes ["Python", "is", "fun"] .
- s_new = “-”.join([l[0][0].upper(), l[1][0], l[2][0].capitalize()])
Then, we join the first letter of each word in l with a hyphen using the join() method and assign it to the variable s_new.
To get the first letter of each word, we use indexing with [0] .
To capitalize the first and third letters, we use the upper() and capitalize() methods respectively.
So, s_new becomes "PYTHON-is-Fun" .
- print(s_new)
Finally, we print s_new using the print() function.
Let’s analyze each of the options and see why they are correct or incorrect.
- Option a: PYTHON-IS-Fun. This is incorrect because it capitalizes the second word “IS”, which is not what the code does.
- Option b: PYTHON-is-Fun . This is correct because it matches the output of the code.
- Option c: Python-is-fun. This is incorrect because it does not capitalize the first word “Python”, which is not what the code does.
- Option d: PYTHON-Is -Fun. This is incorrect because it has an extra space before the hyphen, which is not what the code does.
So, the correct answer is b. PYTHON-is-Fun.
