You can install Python through the official website: https://www.python.org/downloads/#### Requiments
```python
pip install PyPDF2 python-docx pandas beautifulsoup4
```
## Usage
This project can be used as a reference guide for executing shell commands and file handling in Python.
Shell Commands with PythonThis project makes use of Python to execute shell commands. Here are some of the Python commands used in this project:
## Creating and writing to a file
```python
with open("filename.txt", "w") as f:
f.write("Hello, World!")
```
### Reading from a file```python
with open("filename.txt", "r") as f:
print(f.read())
```
### Appending to an existing file```python
with open("filename.txt", "a") as f:
f.write("More text.")
```
### Deleting a file```python
import os
os.remove("filename.txt")
```
### Checking if a file exists```python
import os
os.path.exists("filename.txt")
```
### Creating a directory```python
import os
os.mkdir("directory_name")
```
## Large File HandlingWorking with large files requires a different set of Python commands. Here are some examples:
### Opening a file
```python
file = open('large_file.txt', 'r')
```
### Reading a file line by line```python
with open('large_file.txt', 'r') as file:
for line in file:
print(line)
```
### Reading a specific number of lines```python
from itertools import islice
with open('large_file.txt', 'r') as file:
head = list(islice(file, 5))
```
### Searching within a large file```python
with open('large_file.txt', 'r') as file:
for line in file:
if 'some_text' in line:
print(line)
```
### Writing to a large file```python
with open('large_file.txt', 'w') as file:
file.write('some_text')
```
### Splitting files```python
chunk_size = 1000000 # 1 MB
with open('large_file.txt', 'r') as file:
chunk = file.read(chunk_size)
while chunk:
with open('chunk.txt', 'w') as chunk_file:
chunk_file.write(chunk)
chunk = file.read(chunk_size)
```
## Handling Specific File FormatsPython can read various file formats using specific libraries. Here are some examples:
### Reading PDF files
```python
import PyPDF2
with open('example.pdf', 'rb') as file:
reader = PyPDF2.PdfFileReader(file)
page = reader.getPage(0)
print(page.extract_text())
```
### Reading Word documents```python
from docx import Document
doc = Document('example.docx')
for para in doc.paragraphs:
print(para.text)
```
### Reading Excel files```python
import pandas as pd
data = pd.read_excel('example.xlsx')
print(data)
```
### Reading HTML files```python
from bs4 import BeautifulSoup
with open("example.html") as fp:
soup = BeautifulSoup(fp, 'html.parser')
print(soup.prettify())
```
