Question

For variable product_ code containing a string of letters and digits, (a) Give an if statement that outputs "Verified" if product_code contains both a "Z" and a "9", and outputs "Failed" otherwise. (b) Give a Python instruction that prints out just the last three characters in product_code. Morse Code Encryption/Decryption Program Develop and test a Python program that allows a user to type in a message and have it converted into Morse code, and also enter Morse code and have it converted back to the original message. The encoding of Morse code is given below.

Answer 1

Solution:

a)

# your code goes here

#!/usr/bin/python

str1 = "abcdshJHGD54HgdshZjsdh7329HJGjh"; # Initialization

str2 = "Z"; #Let's search for 'Z' first in the string

val= str1.find(str2) # Find Z

if val!=-1: #if true then find 9

str2= "9"

val1= str1.find(str2)

if val1!=-1:

print "Verified" #Display Verified

else:

print "Failed" #Display Failed

Output:

b)

# your code goes here
#!/usr/bin/python

str1 = "abcdshJHGD54HgdshZjsdh7329HJGjh"; # Initialization
#str2 = "Z"; #Let's search for 'Z' first in the string
val= len(str1)
val= val-3
ch= str1[val]
ch1= str1[val+1]
ch2= str1[val+2]
print ch,ch1, ch2 #Display last three characters of product code
  

Output:

Success comments (0) a stdin Standard input is empty o stdout Gjh
