Which of the following is true about the given python code?fileobject=...
Concept:
The given python code is,
fileobject=open("practice.txt","r")
str = fileobject.readline()
while str:
print(str)
str=fileobject.readline()
fileobject.close()
str = fileobject.readline()
while str:
print(str)
str=fileobject.readline()
fileobject.close()
Explanation:
The readline() is used in the while loop to read the data line by line from the text file. The lines are displayed using the print(). As the end of the file is reached, the readline() will return an empty string. Finally, the file is closed using the close().
Hence the correct answer is To display data from a text file.

Which of the following is true about the given python code?fileobject=...
Explanation:
Opening and Reading a Text File:
- The given Python code opens a text file named "practice.txt" in read mode using the open() function.
- It then reads the first line of the file using the readline() method and stores it in the variable 'str'.
- The code then enters a while loop that iterates as long as the variable 'str' contains a non-empty string.
- Within the loop, it prints the content of the current line (stored in 'str') to the console.
- After printing the content, it reads the next line of the file and updates the 'str' variable with the new content.
- This process continues until the end of the file is reached.
Closing the File:
- Finally, the file object is closed using the close() method. It is a good practice to close the file after reading or writing operations to free up system resources.
Therefore, the given Python code is used to display data from a text file named "practice.txt". It reads the contents of the file line by line and prints them to the console.
