Answer:

"

if 'marsupial' in dictionary:

   del dictionary['marsupial']

else:

   print("The key marsupial is not in the dictionary")

"

Explanation:

So you can use the keyword "in" to check if a certain key exists.

So the following code:

"

if key in object:

   # some code

"

will only run if the value of "key" is a key in the object dictionary.

So using this, we can check if the string "marsupial' exists in the dictionary.

"

if 'marsupial' in dictionary:

   # code

"

Since you never gave the variable name for the variable that references a dictionary, I'm just going to use the variable name "dictionary"

Anyways, to delete a key, there are two methods.

"

del dictionary[key]

dictionary.pop(key)

"

Both will raise the error "KeyError" if the key doesn't exist in the dictionary, although there is method with pop that causes an error to not be raised, but that isn[t necessary in this case, since you're using the if statement to check if it's in the dictionary first.

So I'll just use del dictionary[key] method here

"

if 'marsupial' in dictionary:

   del dictionary['marsupial']

else:

   print("The key marsupial is not in the dictionary")

"

The last part which I just added in the code is just an else statement which will only run if the key 'marsupial' is not in the dictionary.

Fynjy0 [20]

Answer:

batch sequence check.

Explanation:

A batch sequence check can be defined as a strategic and systematic control plan which typically involves the process of inputting a range of numbers comprising a batch and then inputting each serially numbered document.

The steps for checking an event data within a batch using a batch sequence check include the following;

I. You'll enter a range of serial numbers of the document in a batch.

II. You'll enter each serially pre-numbered document one after the other.

III. The input documents are sorted by a computer into a serial (numerical) order, match the sequence number range against the input documents, and then reports any part of the document that is missing, a duplicate and out of range.
