Question

Write a python program to accept string/sentences from the user till the user enters “END” to. Save the data in a text file and then display only those sentences which begin with an uppercase alphabet

Answer 1

Answer:

Python

File and Text Processing

1. File Input/Output

File Input/Ouput (IO) requires 3 steps:

Open the file for read or write or both.

Read/Write data.

Close the file to free the resouces.

Python provides built-in functions and modules to support these operations.

1.1 Opening/Closing a File

open(file, [mode='r']) -> fileObj: Open the file and return a file object. The available modes are: 'r' (read-only - default), 'w' (write - erase all contents for existing file), 'a' (append), 'r+' (read and write). You can also use 'rb', 'wb', 'ab', 'rb+' for binary mode (raw-byte) operations. You can optionally specify the text encoding via keyword parameter encoding, e.g., encoding="utf-8".

fileObj.close(): Flush and close the file stream.

1.2 Reading/Writing Text Files

The fileObj returned after the file is opened maintains a file pointer. It initially positions at the beginning of the file and advances whenever read/write operations are performed.

Reading Line/Lines from a Text File

fileObj.readline() -> str: (most commonly-used) Read next line (upto and include newline) and return a string (including newline). It returns an empty string after the end-of-file (EOF).

fileObj.readlines() -> [str]: Read all lines into a list of strings.

fileObj.read() -> str: Read the entire file into a string.

Writing Line to a Text File

fileObj.write(str) -> int: Write the given string to the file and return the number of characters written. You need to explicitly terminate the str with a '\n', if needed. The '\n' will be translated to the platform-dependent newline ('\r\n' for Windows or '\n' for Unixes/Mac OS).

Answer 2

Answer:

The following Python program performs the desired function:

text  = input()

arr = text.split( )

for i in arr:

  if(i.uppercase() == true):

      print(i)

Explanation:

• We start the code by creating a variable text that will store the text input of the user.
• Then we need to split this input so that we can analyze each word of the text.
• Python gives a split function for splitting the text input.
• Then we iterate over the split words by using a for loop
• If any of the letters of the text is uppercase then we need to print it.
• For doing so, we are using the uppercase() function of the python that returns true if the word is uppercased.
• If it is true then we print the word otherwise we keep moving ahead.
