Question

3. Write Python statements that will do the following: a) Input a string from the user. *** Print meaningful messages along with your output.* b) Print the length of the String. Example input: The sky is blue. Correct output: The length of the string is 16 Incorrect output: 16 c) Print the first character of the string. d) Print the last character of the string. 4. Save the program. Double-check the left edge for syntax errors or warning symbols before you run the program. Fix any errors. Run, test, debug, repeat... until you are sure that your program works correctly. Program 1. string Practice.py is now done.

Answer 1

# Program 1

# input a string from user
s1=input("Enter a string:")

# print the length of the string
print("Length of the string = ",len(s1))

# print first character of the string
print("First character of the string = ",s1[0])

# print the last character of the string
print("Last character of the string = ",s1[-1])

# Program 2
# Create an empty list
mylist=[]

# input 5 float numbers
for i in range(5):
num=float(input())
mylist.append(num)
  
# print the sum of the list elements
print("Sum = ",sum(mylist))

# print the minimum element
print("Minimum element = ",min(mylist))

# print the maximum element
print("Maximum element = ",max(mylist))

# print the average of the list elements
print("Average = ",sum(mylist)/len(mylist))

# remove the last element of the list
mylist=mylist[:-1]

# print the list
print("Mylist = ",mylist)
