Question

consider again the same function
def join(word1, word2, delimiter= ):
joined = str(word1) + str(delimiter) + str(word2)
return joined
what does the function return if we call it as follows:
join(\total\, 3.5, \ is \)
note the space at the start and end of the string \ is \.

Explanation:

Step1: Substitute parameters

Substitute word1 = "total", word2 = 3.5, delimiter = " is " into the formula joined = str(word1)+str(delimiter)+str(word2).

Step2: Convert to string

Convert word1 (already a string), delimiter (string), and word2 (float converted to string) and concatenate.

$$\begin{align*} joined&=\text{"total"}+\text{" is "} + \text{str}(3.5)\\ &=\text{"total"}+\text{" is "} + \text{"3.5"} \end{align*}$$

Step3: Concatenate strings

Concatenate the three strings.

$$ \text{"total is 3.5"} $$

Answer:

"total is 3.5"
