Program to Accept a Sentence and Print only the First Letter of Each Word in Capital Letters Separated by a Full Stop in Python

Below are the ways to Print only the First Letter of Each Word in Capital Letters Separated by a Full Stop in Python.

Using For loop(Static Input)
Using For loop(User Input)

Method #1: Using For Loop (Static Input)

Approach:

Give the sentence/string as static input and store it in a variable.
Split the sentence into a list of words using the built-in split() function.
Take an empty string to say resultstrng and initialize with the null value using “”.
Traverse in this list of words using the For loop.
Check if the word is alphabet or not using the If statement and isalpha() function
If it is true then, Convert the first letter of the word of the string to the upper using the upper function and store it in a variable.
Concatenate dot character to the above variable using string concatenation.
Add this result to resultstrng using string concatenation.
Print resultstrng.
The Exit of the Program.

Below is the implementation:

# Give the sentence/string as static input and store it in a variable.
gvnstrng = 'hello this is btechgeeks 21 python'
# Split the sentence into a list of words using the built-in spit() function.
gvnstrngwords = gvnstrng.split()
# Take an empty string to say resultstrng and initialize with the null value using "".
resultstrng = ""
# Traverse in this list of words using the For loop.
for strngword in gvnstrngwords:
        # Check if the word is alphabet or not using the If statement and isalpha() function
    if(strngword.isalpha()):
                # If it is true then, Convert the first letter of the word of
        # the string to the upper using the upper function and store it in a variable.
        firstchar = strngword[0].upper()
        # Concatenate dot character to the above variable using string concatenation.
        firstchar = firstchar+"."
        # Add this result to resultstrng using string concatenation.
        resultstrng = resultstrng+firstchar

# Print resultstrng.
print(resultstrng)

Output:

H.T.I.B.P.

Method #2: Using For Loop (User Input)

Approach:

Give the sentence/string as user input using the input() function and store it in a variable.
Split the sentence into a list of words using the built-in split() function.
Take an empty string to say resultstrng and initialize with the null value using “”.
Traverse in this list of words using the For loop.
Check if the word is alphabet or not using the If statement and isalpha() function
If it is true then, Convert the first letter of the word of the string to the upper using the upper function and store it in a variable.
Concatenate dot character to the above variable using string concatenation.
Add this result to resultstrng using string concatenation.
Print resultstrng.
The Exit of the Program.

Below is the implementation:

# Give the sentence/string as user input using the input() function
# and store it in a variable.
gvnstrng = input('Enter some random string/sentence = ')
# Split the sentence into a list of words using the built-in spit() function.
gvnstrngwords = gvnstrng.split()
# Take an empty string to say resultstrng and initialize with the null value using "".
resultstrng = ""
# Traverse in this list of words using the For loop.
for strngword in gvnstrngwords:
        # Check if the word is alphabet or not using the If statement and isalpha() function
    if(strngword.isalpha()):
                # If it is true then, Convert the first letter of the word of
        # the string to the upper using the upper function and store it in a variable.
        firstchar = strngword[0].upper()
        # Concatenate dot character to the above variable using string concatenation.
        firstchar = firstchar+"."
        # Add this result to resultstrng using string concatenation.
        resultstrng = resultstrng+firstchar

# Print resultstrng.
print(resultstrng)

Output:

Enter some random string/sentence = good morning this is btechgeeks online coding 24 platform for btech students
G.M.T.I.B.O.C.P.F.B.S.
