Python编程作业求助：如何实现wordSalad函数？

Hey there! This is a pretty straightforward task—let's break it down and build the function you need.

First, let's recap the requirements clearly:

• The function must be named wordSalad
• It takes 4 string parameters
• It returns a formatted string following the pattern: I love [参数1] and [参数2] with [参数3] and [参数4]

The Simplest Implementation (Using F-Strings) #

Python's f-strings (available in Python 3.6+) are perfect here because they let you directly embed variables into strings in a clean, readable way. Here's the code:

def wordSalad(arg1, arg2, arg3, arg4):
    return f"I love {arg1} and {arg2} with {arg3} and {arg4}"

Testing the Function #

Let's run the example test case to verify it works:

print(wordSalad('Bob', 'Joe', 'lemonade', 'pizza'))

Output: I love Bob and Joe with lemonade and pizza

Alternative: Using str.format() #

If you need compatibility with older Python versions (pre-3.6), you can use the str.format() method instead:

def wordSalad(arg1, arg2, arg3, arg4):
    return "I love {} and {} with {} and {}".format(arg1, arg2, arg3, arg4)

This will produce exactly the same result as the f-string version.

Either approach will get the job done, but f-strings are generally preferred these days for their readability and simplicity.
