Question

Write a Python program in this Jupyter Notebook. This program will allow a user to choose from a menu to print various text shapes includeing rectangle, triangle, and diamond as well as a set of numbers in a pattern. This program will allow the user to select the type, the size and/or the fill character for a shape. Your program will verify user inputs such as size for certain range specifications, depending on the shapes.

Answer 1

Solution:-

def rectangle(): # function to print the rectangle.
rows = int(input("Please Enter the Total Number of Rows : "))
columns = int(input("Please Enter the Total Number of Columns : "))
ch=input("enter the fill character the shape ")
print("Rectangle ")
for i in range(rows):
for j in range(columns):
print('%c' %ch, end = ' ')
print()
# Function for printing triangle
def triangle(n):
ch=input("enter the fill character the shape ")

k = 2*n - 2
  
# outer loop to handle number of rows
for i in range(0, n):
  
# inner loop to handle number spaces
# values changing acc. to requirement
for j in range(0, k):
print(end=" ")
  
# decrementing k after each loop
k = k - 1
  
# inner loop to handle number of columns
# values changing acc. to outer loop
for j in range(0, i+1):
  
# printing stars
print("%c " %ch, end="")
  
# ending line after each row
print("\r")   
  
  
def Diamond(rows):
ch=input("enter the fill character the shape ")
n = 0
for i in range(1, rows + 1):
# loop to print spaces
for j in range (1, (rows - i) + 1):
print(end = " ")
  
# loop to print star
while n != (2 * i - 1):
print("%c" %ch , end = "")
n = n + 1
n = 0
  
# line break
print()
  
k = 1
n = 1
for i in range(1, rows):
# loop to print spaces
for j in range (1, k + 1):
print(end = " ")
k = k + 1
  
# loop to print star
while n <= (2 * (rows - i) - 1):
print("%c" %ch , end = "")
n = n + 1
n = 1
print()   
  
#function to PRINT NUMBER PATTERN   
def printNos(n):
print("the pattern:\n")
for row in range(1, n+1):
for column in range(1, row + 1):
print(column, end=' ')
print("")

print("************MAIN MENU**************")
print("""Please select your choice -\n
1. print Rectangle\n
2. print traingle\n
3. print diamond\n
4. print the number pattern\n""")
  
  
# Take input from the user
select = input("Select your choice form 1, 2, 3, 4 :")
  

# control the menus using if-else and printing the shape as per users choice
if select == '1':
rectangle()
  
elif select == '2':
s=int(input("enter the size of traingle"))
triangle(s)
  
elif select == '3':
aa=int(input("ENTER THE SIZE OF THE DIAMOND"))
Diamond(aa)
  
elif select == '4':
s=int(input("enter the size of the pattern : \n"))
printNos(s)
  
  

else:
print("Invalid input")
  
  
  

Output:-

* **** ***** **MAIN MENU************** Please select your choice - 1. print Rectangle 2. print traingle 3. print diamond 4. print the no pattern Select your choice form 1, 2, 3, 4 :3 ENTER THE SIZE OF THE DIAMOND10 enter the fill character the shape *
