Prerequisite: Opening, closing a file/open(), close() functions in Python

1) Writing content (using file_object.write())

To write content in a file, we use write() function, which is called with the file object name.



2) Reading content (using file_object.read())

To read the content of a file, we use read() function, which is called with the file object name.



It returns the content of the file in string format.


Here, we are creating a file, writing data to the file, closing the file and again reading the file in read only mode, reading the data, closing the file.

# opening a file in write mode
fo = open("data.txt","wt")

# data to write in the file
data = "Hello friends, how are you?"

# writing data to the file
# closing the file
print("Data is written and file closed.")

# clearing the variable 
data = ""

# opening the file in read mode
fo = open("data.txt","rt")

# reading the data and printing
data = fo.read()
print("file's content is: ")

# closing the file 


Data is written and file closed.
file's content is:
Hello friends, how are you?
