I have a problem as i am a newbie. I am learning how to code python from the book by dierbach- intro to comp sci using python.But i am confused on how the author thought about the code. The author did not say why.
If you look at the diagram i attached you will see that the author says something like: "if the month is May, then add 2 to value, else".
My question is why add 2 and not 5 or 8.
I wnat to know why he increments the value by random numbers.

Please explain this to me as I dont understand.

Thank you very much for reading and help

See how you have the first five steps, could you give us the extra steps after that too? We won't know why unless we know what he is going to do with value.

Also, I have a feeling this will be more mathematical than programming (I'm assuming you want to know how he gets the day of the week from the date).

EDIT: I think because if the first day of January was a Monday (give that a value of 0) then the first day of May will be Wednesday (so add two onto it). For example, Friday was the first day of January this year and Sunday was the first day of May, so he added 2 to the value. I guess he will do the mod function later on somewhere (at the end) to finally get the day of the week.

Hey!

How do you generate a set of random numbers and allocate it to the user on python. Like say if they input the question 'How do i fix my computer?' , they should be given a unique id from a set of random numbers and yeah they will be basically given a case number which will then be sent off to a technician.

How would I code this with python?

Thanks!

Q: Write a function called pattern_sum that receives two single digit positive integers, (k and m) as parameters and calculates and returns the total sum as:
k + kk + kkk + .... (the last number in the sequence should have m digits)
For example, if the two integers are:

(4, 5)
Your function should return the total sum of:
4 + 44 + 444 + 4444 + 44444
Notice the last number in this sequence has 5 digits. The return value should be:
49380


Iam trying to use Lambda to solve this question

please help def two(a, b):

total = list(map(lambda i: int(str(a) * i), range(1, b+1)))
return total[-1]
two(4, 5))this is what i have so far

i would like to use it with out having to splice a list
is there a way?

I am currently doing conouting and coding in Visual Basic, however im struggling with arrays. The question is: Write a program which has two arrays. One array contains a list of questions, and the other contains the corresponding answers. Your program should randomly select questions from the question array, allow the user to enter their answer, and then check this using the answer array.
Any advice on how to create the arrays, how to input the questions and answers and how to make sure the answers are with the questions
Thank you!!!

Hi,

How do I make make python prompt user to enter an valid input if they enter blank space,punctuation or integer?
The user should be prompted to enter a valid response like 5 times and if they don't the program should exit. But I'm struggling to d this as I am only a beginner.

E.g
resolved=("Is your issue solved?"
if resolved..

Thanks

Here you go.

EDIT: I used semi-colons but they are not necessary when coding in Python. I learn other languages and so I have grown a habit of using it.

EDIT: This forum translates my code differently from how I have written it and so there may be minor errors - easy fix though!

counter = 0;

loop = True;

while loop == True:

response = input("";

punctuations = [""]; # insert punctuations here

if response == int or " " or punctuations:
counter = counter + 1;
print("ERROR.";
print(counter);

if counter >= 5: # you can use if statements within if statements (nesting is thing, ya know)
loop = False; # you were not explicit enough on how you want to end the program but this is where you tell python on how you want to end the program
print("END.";

else:
print(); # i like to add this if else statements are empty but it's not necessary


Would it be better to writecounter += 1instead of counter = counter + 1

Absolutely terrible and inefficient way of doing this. Look up on the Regular Expressions library please.
