Question

My code(python):

strng = input("Enter a sentence or phrase:\n\n")
print ("You entered:", strng)
def get_num_of_characters(strng):
    countChar = 0
    for i in range(0, len(strng)):
        countChar = countChar + 1
    return countChar;
def output_without_whitespace(strng):
    strWithoutSpace = ""
    for i in range(0, len(strng)):
        if strng[i] != ' ':
            strWithoutSpace = strWithoutSpace + strng[i]
    return strWithoutSpace;
print ("\nNumber of characters:",get_num_of_characters(strng))
print ("String with no whitespace:",output_without_whitespace(strng))
 

 

(1) Prompt the user to enter a string of their choosing. Output the string. 

Ex:

Enter a sentence or phrase:

The only thing we have to fear is fear itself.

You entered: The only thing we have to fear is fear itself.

(2) Complete the get_num_of_characters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. 

(3) Extend the program by calling the get_num_of_characters() function and then output the returned result. 

(4) Extend the program further by implementing the output_without_whitespace() function. output_without_whitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the output_without_whitespace() function in main(). 

Ex:

Enter a sentence or phrase:

The only thing we have to fear is fear itself.

You entered: The only thing we have to fear is fear itself. Number of

characters: 46 String with no whitespace: Theonlythingwehavetofearisfearitself.

**Comparison of Output for String Manipulation Tasks**

This image presents a comparison of string manipulation results from a programming exercise. The purpose is to identify discrepancies between a user's output and the expected output. The exercise involves inputting a sentence and generating a string without whitespace.

### Example 1:

**Input:**
- Sentence: "The only thing we have to fear is fear itself."

**Your Output:**
- You entered: "The only thing we have to fear is fear itself."
- Number of characters: 46
- String with no whitespace: Theonlythingwehavetofearisfearitself.
- Note: The final line inaccurately states "String with no whitespace: None" which is highlighted.

**Expected Output:**
- You entered: "The only thing we have to fear is fear itself."
- Number of characters: 46
- String with no whitespace: Theonlythingwehavetofearisfearitself.

### Example 2:

**Input:**
- Sentence: "The rain in Spain stays mainly in the plain."

In both tasks, users are asked to remove spaces from given phrases to check consistency in character handling. Highlighted sections indicate deviations from expected results, suggesting an error in the user's output configuration.

This exercise is useful for understanding string operations, particularly in removing whitespace for applications in data processing, programming, and software testing.
