There is actually a dictionary comprehension to create a dictionary, just as there is a list comprehension that creates a list.

See if you can identify the meaning of each of the comprehensions in the following code segment. $$ You would be able to execute these statements if you copied $($or cut$-$and$-$paste$)$ them one at a time into the Shell.

word $=$ 'Mississippi'

print$([$word$[$i$]$ for i in range$(1,$len$($word$))$ if word$[$i$]==$word$[$i$-1]])$

print$(\text{'}\text{'}.$join$([$word$[0]]+[$word$[$i$]$ for i in range$(1,$len$($word$))$ if word$[$i$]!=$word$[$i$-1]]))$

$1)$ What is the first list comprehension collecting into the list?

$2)$ What is the second comprehension collecting into its list?

$3)$ What is the $\text{'}\text{'}\text{'}.$join doing to that list?

$4)$ What earlier recitation produced results like these?$$

$5)$ What is your opinion about this code as compared to that earlier recitation?
