Here is Python logic that shows Parse and Read Different Files in Python. The formats are XML, JSON, CSV, Excel, Text, PDF, Zip files, Images, SQLlite, and Yaml.
Python Reading Files
import pandas as pd
import json
import xml.etree.ElementTree as ET
from PIL import Image
import pytesseract
import PyPDF2
from zipfile import ZipFile
import sqlite3
import yaml
Reading Text Files
# Read text file (.txt)
def read_text_file(file_path):
with open(file_path, 'r') as file:
text = file.read()
return text
Reading CSV Files
# Read CSV file (.csv)
def read_csv_file(file_path):
df = pd.read_csv(file_path)
return df
Reading JSON Files
# Read JSON file (.json)
def read_json_file(file_path):
with open(file_path, 'r') as file:
json_data = json.load(file)
return json_data
Reading Excel Files
# Read Excel file (.xlsx, .xls)
def read_excel_file(file_path):
df = pd.read_excel(file_path)
return df
Reading PDF files
# Read PDF file (.pdf)
def read_pdf_file(file_path):
with open(file_path, 'rb') as file:
pdf_reader = PyPDF2.PdfReader(file)
text = ""
for page in pdf_reader.pages:
text += page.extract_text()
return text
Reading XML Files
# Read XML file (.xml)
def read_xml_file(file_path):
tree = ET.parse(file_path)
root = tree.getroot()
return root
Reading Image Files
# Read image file (.jpg, .png, etc.)
def read_image_file(file_path):
image = Image.open(file_path)
text = pytesseract.image_to_string(image)
return text
Reading Zip Files
# Read compressed file (.zip, .tar.gz, etc.)
def read_compressed_file(file_path):
with ZipFile(file_path, 'r') as zip_file:
files = zip_file.namelist()
return files
Reading SQLLite
# Read SQLite database file (.db)
def read_sqlite_file(file_path):
conn = sqlite3.connect(file_path)
cursor = conn.cursor()
cursor.execute("SELECT * FROM table_name")
data = cursor.fetchall()
return data
Reading YAML Files
# Read YAML file (.yaml)
def read_yaml_file(file_path):
with open(file_path, 'r') as file:
yaml_data = yaml.load(file, Loader=yaml.SafeLoader)
return yaml_data
# Usage examples
txt_file = "/path/to/text/file.txt"
txt_data = read_text_file(txt_file)
csv_file = "/path/to/csv/file.csv"
csv_dataframe = read_csv_file(csv_file)
json_file = "/path/to/json/file.json"
json_data = read_json_file(json_file)
excel_file = "/path/to/excel/file.xlsx"
excel_dataframe = read_excel_file(excel_file)
pdf_file = "/path/to/pdf/file.pdf"
pdf_text = read_pdf_file(pdf_file)
xml_file = "/path/to/xml/file.xml"
xml_data = read_xml_file(xml_file)
image_file = "/path/to/image/file.jpg"
image_text = read_image_file(image_file)
zip_file = "/path/to/compressed/file.zip"
compressed_files = read_compressed_file(zip_file)
sqlite_file = "/path/to/sqlite/file.db"
sqlite_data = read_sqlite_file(sqlite_file)
yaml_file = "/path/to/yaml/file.yaml"
yaml_data = read_yaml_file(yaml_file)
Note that some functionalities, like reading images or extracting data from an SQLite database, may require additional libraries to be installed, such as pytesseract for image processing and SQLite3 for database manipulation. Make sure you have those libraries installed before running the code.
Conclusion
In conclusion, the ability to read different file formats is a crucial skill in Python programming, enabling developers to handle a diverse range of data sources.
