Question

1. Write a Python program (with comments) to do the following:
   1. Assign the value '2+1' to a variable str1.
   2. Use the eval() function to evaluate str1and assign the result to a variable num1.
   3. Ask the user to input their birth month and assign it to a variable month and then print it with a suitable message.
   4. Determine the number of letters in month and display the result with a suitable message.
   5. Determine how many times the letter 'r ' occurs in month and display the result with a suitable messag
   6. Concatenate the string month num1 times and print it with a suitable message.
   7. Print the last 2 characters of month in uppercase, with a suitable message.

Answer 1

#*******************main.py*************************#

str1 = '2+1' #assign variable
num1 = eval(str1)#evaluate funtion
month = input("Enter birth month: ")#prompt for month
print("Birth month is: ",month)#print month
print("Number of letter in Birth month: ",len(month))#length of moth
print("Letter r in the month: ",month.count('r'))#occurrence of r
conctString = "";
while(num1!=0):
conctString = conctString+month;
num1= num1-1;
print("Concatinating String ",conctString)#print conctString
print("Last two letter in Upper case: ",month[(len(month)-2):(len(month))].upper())#last two upper
