In this assignment, you will play the role of a data engineer at a manufacturing company. The company

has a legacy system that stores logs of manufacturing batches in a pecullar string format. Your task is to

validste and extract information from these log strings.

A valid log string adheres to the followine format

Batch Prefix. Each batch within the strinc starts with the prefix $\text{'}B\text{'}($case sersitive$).$

Batch ID$.$ Following the preflx, there is a batch ID consisting of exactly four diges.

Product Code: Nert, there is a product code that starts with $\text{'}P\text{'}($case sensitive$)$ followed by

eactly two letters $($uppercase$-$case senaitive$).$

Quantity: Then, there is a quantty section that starts with $\text{'}Q\text{'}($case sencitive$)$ followed by an

integer above sero representing the quartity of products in the batch. Leading seros are ok$,$ for

eample, C$0050$ is OK$,$ and $050$ is OK$.$ However, the leading zero should be eliminated once the

quantity number is extracted. For example, $0050$ is $50$ once extracted. Note that the quarerty

output is an integer, not a strine.

Date: Finally, there is a date section that starts with $\text{'}$D$\text{'}($case sensitive$)$ followed by a date in the

format monhaudo

Its $($YrmMDO$)$ length should be eight characters.

The first four characters represent the year, which thould be between $2000$ and $2019.$

The neat two characters represent the month, which should be between $01$ and $12.$

The last two characters represent the day, which should be between $01$ and $31($although

not all months have $31$ dara, we II igore this detal for simplicity $-$ no need to check for

leap year for example, $20230229$ is ok$,20230931$ is ok$)$

The string can contain multiple batches, each adhering to the format described above

Your task is to wribe a Python function that takes this log strine as input and retums a list of dictionaries

containing information about each batch if the string is valid. if the string is imalid, return "imalidr. The

"imalid" return value is a string value, not a Boclean value.

Example::

$"$B$1234$PABCS$0$D$20230908"$ is valid and should returnc

IF'Datch ID$\text{'}$: $\text{'}1234\text{'},$ 'Product Code': $\text{'}$A$8\text{'},$ 'Quantity': $50,$ 'Date': $\text{'}202309087]$

$"$b$1234$pasoso$0202$s$0905"$ is imalid $($the botch $$arts with a lowercase $"$b$)$ and should return

invald

$"$B$1234$P$3$BCS$0$D$20230908"$ is imalid $($product code contains a digit$).$

invald

$"$B$1234$PABCSODa$023$Ag$0$s$"$ is invald $($dste contains a non$-$dieit character$).$

invalid

$"$B$1234$PABC$50$D$202305085$S$673$PXRC$30$C$20230909"$ is valid $[$contains multiple valid batches$)$

and should returnc

I$[$Batch $10\text{'}$: $\text{'}1236\text{'},$ 'Product Code': $\text{'}$AB$\text{'},$ 'Quantity': $50,$ 'Date': $\text{'}202309002,[$Batch $10\text{'}$: $\text{'}$Y$678\text{'},$

'Product Code': $\text{'}$XYr$,$ 'Quantity': $30,$ 'Date': $\text{'}20230909\text{'}1]$

$"$B$1234$PABC$0050020230903$B$5678$PKYO$0030$D$20230909"$ is vald $($contains multiple valid

batches$)$ and should retum:

I$[$Batch ID$\text{'}$: $\text{'}1234\text{'},$ Product Code': $\text{'}$AB$\text{'},$ 'Quantity': $50,$ 'Date': $\text{'}202309087,($Batch ID$\text{'}$: $\text{'}$Y$678\text{'},$

"Product Code': $\text{'}$Xr$$ 'Qusntity': $30,$ 'Date': $\text{'}20230909\text{'}1]$

Implementation Details:

Use Pyehon built$-$in functions and data types to solve this task.

The function should be able to handle strings containing one or more batches.

IMPORTANT: $$

You must implement your function with the name validate$\_$and$\_$extract$\_$log in a file named

manufacturelog py$.$ Your program will fail, and you will recelve a zero if you do not follow this naming

comention. The names are case$-$sensitive$.$

DO NOT include any print statements in your code. You should remove all print statements before

submitting your assignment code.

DO NOT include your own test cases or test functions $($for testing your validate$\_$and$\_$extract$\_$log$))$

function$)$ in your code.

It is OK if you have other supporting functions in addition to the validate$\_$and$\_$extract$\_$log$($s$)$

function.

You can only use Python built$-$in functions to write this program. You are not allowed to use any

imported modules, packages, or libraries such as pandas, NumPy, math, etc. The goal of this

assignment is to practice:
