· After you create the object (e.g., Q1), DO NOT PRINT! Your file should something look like this:

 

Q1 = [‘Hello’]

Q2 = x[3:]

Note: Be sure to define your functions in reference to previously created strings/lists as opposed to passing a string/list as an argument to the function.

 

· Create a string called Q1 with the characters “Data Science for all!”

 

· Create a function called Q2 that loops through and prints each character in Q1.

 

For example: The string “Data” would print:

D

a

t

a

 

· Create a function called Q3 that loops through each character in Q1 and prints “A” for each character.

 

For example: The string “Data” would print:

A

A

A

A

 

· Create a list called Q4 with the following five items: DTSC 520, DTSC 550, DTSC 575, DTSC 600, DTSC 650

 

· Create a function called Q5 that loops through and prints each item in Q4.

 

For example:

DTSC 520

DTSC 550

DTSC 575

DTSC 600

DTSC 650

 

· Create a function called Q6 that loops through and prints all values less than 50, starting with 2, such that the value is doubled each iteration.

 

For example:

2

4

8

16

32

 

· Create a list containing the following numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. Assign it to Q7.

 

· Create a function called Q8 that loops through Q7, adding all the numbers together and returning the sum.

 

For example: When you invoke Q8, it should return 129 since 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 = 129.

 

· Create a function called Q9 that uses a loop to determine how many times, starting with the number 3, a number can be squared until it reaches at least a twenty digit number

 

For example: It takes three times, starting with the number 3, that a number can be squared until it reaches a four digit number: 3^2 = 9, 9^2 = 81, 81^2=6561).

IntroPythonA3 – FOR CREDIT

· Create a .ipynb file called IntroPythonA3credit.ipynb and complete the following.

Note: Only the words should be strings in these lists.

 

· Create a list called Q1 containing the following three items in the given order: one , 1 , and 1.0 .

 

· Create a list called q2 containing the following three items in the given order: two , 2 , and 2.0 . Without redefining (or recreating) the list, alter the list such that the second item in the list becomes dos . Assign it to Q2.

 

· Create a list called q3 containing the following three items in the given order: three , 3 , and 3.0 . Without redefining (or recreating) the list, attach tres to the end of q3’s list. Assign it to Q3.

 

· Create a list called q4a containing the following three items in the given order: four , 4 , and 4.0 . Create another list called q4b containing the following four items in the given order: eight , 8 , 8.0 , and ocho . Attach q4b’s list to the end of q4a’s list, creating a list of length 7. Assign it to Q4.

 

· Create a list called q5a containing the following two items in the given order: five and 5 . Create another list called q5b containing the following four items in the given order: nine , 9 , 9.0 , and nueve . Attach the entire q5b to the end of q5a’s list, creating a list of length 3 (tip: think of a list inside a list). Assign it to Q5.

 

· Find the length of q5b and assign it to Q6.

 

· Multiply q5b by 3 and assign it to Q7.

 

· Assign to Q8 the last item in Q5 by indexing the Q5 list.

IntroPythonA1 ● Create a .ipynb file called IntroPythonA1.ipynb and complete the following. ● For this assignment you can not load any libraries. Subsequent assignments might

require libraries, so please read instructions carefully. ● After you create the object (e.g., Q1), DO NOT PRINT! Your file should something look

like this:

Q1 = [‘Hello’] Q2 = x[3:]

● Create a string called Q1 with the characters “Welcome to EU!”

● Slice Q1 to obtain only EU! and assign it to Q2

● Slice Q1 to obtain only me to and assign it to Q3 (note the space after ‘to’)

● Create a list called Q4 that includes: ○ Eric Camacho ○ Elmer Felicitas ○ Shankar Lucrece ○ Gitta Nevena ○ Rasmus Tarquinius

● Create a list called Q5 that includes: ○ 7 ○ ‘7’ ○ ‘Seven’ ○ 7.0

● Slice Q4 and obtain only [‘Gitta Nevena’, ‘Rasmus Tarquinius’]. Assign it to Q6

● Slice Q5 to obtain only [‘7’, ‘Seven’] Assign it to Q7.

 

 

● Create a list called mylist that contains [4, 8, 11, 3, 19, 2, 5, 8, 12, 9]. Slice that list to obtain the corresponding:

Q8: [4, 8, 11]

Q9: [8, 12, 9]

Q10: [11, 3, 19, 2]

Q11: [2, 5]

SOLUTION

A code walk-through, also known as code review, is a process of thoroughly examining the source code of a software program in order to find and fix bugs, improve code quality, and share knowledge among team members. During a code walk-through, a team of developers and stakeholders review the code line by line, discussing its design, implementation, and compliance with coding standards and best practices. The goal of a code walk-through is to identify and address any issues or improvements before the code is released to production.

Here is a typical process for conducting a code walk-through:

  1. Preparation: The code author prepares the code for review and provides any relevant documentation or context. The code reviewers familiarize themselves with the code and identify areas of concern or interest.
  2. Scheduling: A time is scheduled for the code walk-through and the attendees are confirmed.
  3. Code Discussion: The code walk-through begins with a discussion of the high-level design and architecture of the code. This is followed by a detailed review of the code, line by line, with the code author and reviewers discussing any issues or questions that arise.
  4. Feedback and Improvements: As the code is reviewed, the code author and reviewers discuss potential improvements and identify any bugs or areas that need to be fixed. The code author takes note of the feedback and makes any necessary changes.
  5. Next Steps: After the code walk-through is completed, the code author implements any changes and the reviewers follow up to ensure that the changes have been made.
  6. Closing: The code walk-through is considered complete when the code is deemed to be of high quality and ready for release.

Code walk-throughs can be a valuable tool for improving code quality and ensuring that software is free of bugs and vulnerabilities. By engaging in regular code walk-throughs, teams can foster a culture of collaboration, knowledge sharing, and continuous improvement.
