Question

question 18 which lines of code will print the following output: this class is computer science 01 and pre-ap print(\this\, \class\, \is\, \computer\, \science\, \01\, \and\, \pre-ap\, sep=\\) print(\this class is computer science 01 and pre-ap\) print(\this\, \class\, \is\, \computer\, \science\, \01\, \and\, \pre-ap\) print(\this\, \class\, \is\, \computer\, \science\, \01\, \and\, \pre-ap\, end=\\)

Explanation:

1. For print("This class is Computer Science 01 and PRE - AP"): This directly prints the exact string we need as the output, so it's correct.
2. For print("This", "class", "is", "Computer", "Science", "01", "and", "PRE - AP"): In Python, when we pass multiple strings as arguments to the print function without a sep parameter, the default separator is a space. So these strings will be concatenated with spaces in between, resulting in the desired output.
3. For the first option print("This", "class", "is", "Computer", "Science", "01", "and", "PRE - AP", sep = ""): The sep is set to an empty string, so the strings will be concatenated without any space, which is not what we want.
4. For the last option print("This", "class", "is", "Computer", "Science", "01", "and", "PRE - AP", end = " "): The end parameter is used to set what comes after the printed content. Here it adds a space at the end, but it doesn't affect the concatenation of the input strings (the default sep is still a space, but the end is an extra space at the end which is not part of our desired output).

Answer:

B. print("This class is Computer Science 01 and PRE - AP")
C. print("This", "class", "is", "Computer", "Science", "01", "and", "PRE - AP")
