Study guide Intro to PYTHON questions:

25) Write the code that will generate this output using only while loops and if statements (no string multiplication). ###AAAAAAAA### ###BBBBBBBB### ###CCCCCCCC### ###AAAAAAAA### ###BBBBBBBB### ###CCCCCCCC###

Answer 1

25)Code:

a=1
while(a<3): #two times loop for first 3 lines and second 3 lines
    b=1
    while(b<4): #loop for each line means A,B,C
        c=1
        if(b==1):
            s='A'
        elif(b==2):
            s='B'
        else:
            s='C'
        while(c<15): #loop for print 3#'s and 8 Characters(A or B or C) and 3 #'s
            if(c<=3):
                print("#",end="")
            elif(c>3 and c<12):
                print(s,end="")
            else:
                print("#",end="")
            c=c+1
        print("")
        b=b+1
    a=a+1

Code snippet 25:

a=] while (a<3): #two times loop for first 3 lines and second 3 lines b=1 while (b<4): #loop for each line means A,B,C c=1 if (b==1): S='A' elif (b==2): s='B' else: s='C' while (c<15): #loop for print 3#'s and 8 Characters (A or B or C) and 3 #' if (c<=3): print("#", end="") elif (c>3 and c<12): print (s, end="") else: print("#", end="") c=c+1 print("") b=b+1 a=a+l

Output 25:

###AAAAAAAA### ###BBBBBBBB### ###CCCCCCCC### ###AAAAAAAA### ###BBBBBBBB### ## #CCCCCCCC# ##

26) Code:

n=int(input("Size?")) #asking input size
i=1;
j=1;
while(i<=n):
    j=1;
    while(j<=i):
        print("*",end="");
        j=j+1;
    print()
    print()
    i=i+1

Code snippet 26)

naint (input ("Size?")) #asking input size i-l; j=1; while(ic=n): j=1; while (j<=i): print("*", end=""); j=j+1; print() print() i-i+

Output 26:

Size25

23)Code:

def study_calculator():
    a=int(input("How many weeks do you want to calculate? "))
    i=1
    c=0;
    while(i<=a):
       b=int(input("How many hours did you spend for this week? "))
       c=c+b;
       i=i+1;
    print("Total amount of hours spent on study for",a,"weeks are",c)
study_calculator()
  

Code snippet 23:

def study_calculator(): a=int(input ("How many weeks do you want to calculate? ")) i=1 c=0; while (i<=a): b=int (input ("How many hours did you spend for this week? ")) C=C+b; i=i+1; print ("Total amount of hours spent on study for", a, "weeks are", c) study_calculator()

Output 23:

How many weeks do you want to calculate? 3 How many hours did you spend for this week? 20 How many hours did you spend for this week? 30 How many hours did you spend for this week? 30 Total amount of hours spent on study for 3 weeks are 80

22)Code:

def total_volume():
    width=int(input("please input a width:"))
    while(1):
        if(width<=0):
            print("Width must be positive")
            width=int(input("please input a width:"))
        if(width>0):
            break
    length=int(input("please input a length:"))
    while(1):
        if(length<=0):
            print("length must be positive")
            length=int(input("please input a length:"))
        if(length>0):
            break
    height=int(input("please input a height:"))
    while(1):
        if(height<=0):
            print("height must be positive")
            height=int(input("please input a height:"))
        if(height>0):
            break
    units=(input("please input a units:"))
    vol=width*length*height
    print("The volume of the object is",vol,end=" ");
    print(units,"^3");
total_volume()

Code snippet 22:

def total_volume(): width=int (input ("please input a width:")) while(1) : if(width<=0): print ("Width must be positive") width=int (input ("please input a width:")) if(width>0): break length=int (input("please input a length:")) while(1) : if(length<=0): print("length must be positive") length=int (input ("please input a length:")) if(length>0): break height=int (input ("please input a height:")) while(1) : if (height<=0): print ("height must be positive") height=int (input ("please input a height:")) if (height>0): break units=(input("please input a units:")) vol=width length height print("The volume of the object is", vol, end=" "); print (units,"23"); total_volume()

Output 22:

please input a width:3 please input a length:3 please input a height:3 please input a units:in The volume of the object is 27 in ^3
