The program is an illustration of conditional statements.
Conditional statements are statements whose execution is dependent on the truth value of the condition.
The checkCharacter() method in Python, where comments are used to explain each line is as follows:
#This defines the method
def checkCharacter(myStr,indx):
#This checks if the character at the index, is a letter
if myStr[indx].isalpha():
#If yes, it returns "Letter"
return "Letter"
#This checks if the character at the index, is a digit
elif myStr[indx].isdigit():
#If yes, it returns "Digit"
return "Digit"
#This checks if the character at the index, is a white space
elif myStr[indx] == " ":
#If yes, it returns "White Space"
return "White Space"
#If all the above conditions are false
else:
#It returns "Unknown Character"
return "Unknown Character"
The string to return depends on the character at the index.
