2. Write a program with a function that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argument is "hello. my name is Joe. what is your name?" the function should return the string "Hello. My name is Joe. What is your name?" The program should let the user enter a string and then pass it to the function. The modified string should be displayed.

Following are the code to this question:

def capital(val):#defining a method that takes string value as parameter

   x=True#defining boolean variable

   r=''#defining string variable  

   for i in val:#defining loop to convert the first character into upper case

       if i.isalpha() and x:#defining condition to check input value is string

           r=r+i.upper()#change value into uppercase and hold value in r variable

           x=False#assign value false in boolean variable

       elif i=='.' or i=='?' or i=='!':#check symbols

           r=r+i#add value in r variable

           x=True#assign value True in boolean variable

       else:

           r=r+i#add all value in r variable

   return r#return r variable value

val=input()#input value in val variable

print(capital(val))#called the function which print the return value

Output:
