Input/Output (I/O) and file processing are essential aspects of programming that involve the reading and writing of data to and from various sources, such as files, standard input/output streams, and other external devices. Here's an overview of I/O and file processing:
Standard Input/Output (I/O):
Standard Output (stdout):
Output to the console or terminal.
In many programming languages, the print statement or function is used for standard output.
python
Copy code
print("Hello, World!")
Standard Input (stdin):
Reading input from the user through the console or terminal.
In Python, the input function is commonly used.
python
Copy code
name = input("Enter your name: ")
print(f"Hello, {name}!")
File Processing:
Opening and Closing Files:
Files are opened using the open function and closed using the close method.
python
Copy code
Opening a file in read mode
file = open("example.txt", "r")
Reading content from the file
content = file.read()
print(content)
Closing the file
file.close()
Reading from a File:
Reading methods include read, readline, and readlines.
python
Copy code
Reading the entire content of the file
content = file.read()
Reading one line at a time
line = file.readline()
Reading all lines into a list
lines = file.readlines()
Writing to a File:
Files can be opened in write mode ("w") or append mode ("a").
Writing methods include write and writelines.
python
Copy code
Opening a file in write mode
file = open("example.txt", "w")
Writing content to the file
file.write("This is a sample text.")
Closing the file
file.close()
Using Context Managers (with statement):
The with statement ensures that the file is properly closed, even if an exception occurs.
python
Copy code
with open("example.txt", "r") as file:
content = file.read()
Handling Different File Formats:
Different file formats (e.g., text files, CSV, JSON, XML) require specific parsing methods.
python
Copy code
import json
Reading from a JSON file
with open("data.json", "r") as json_file:
data = json.load(json_file)
Writing to a JSON file
with open("output.json", "w") as output_file:
json.dump(data, output_file)
Exception Handling:
File-related operations may raise exceptions (e.g., FileNotFoundError).
Proper error handling is crucial for robust file processing.
python
Copy code
try:
with open("nonexistent_file.txt", "r") as file:
content = file.read()
except FileNotFoundError:
print("File not found.")
Binary File Operations:
Binary files can be processed using modes like "rb" (read binary) and "wb" (write binary).
python
Copy code
with open("binary_data.bin", "rb") as binary_file:
data = binary_file.read()
Random Access:
Some file systems support random access, allowing reading or writing at any position within the file.
python
Copy code
with open("example.txt", "r") as file:
file.seek(5) # Move to the 6th character
content = file.read(10) # Read the next 10 characters
File processing is a fundamental part of programming for reading and storing data persistently. Understanding I/O operations and file handling is crucial for developing applications that interact with external data sources.
