Before & After: Code Transformation with PT Dev Utility
See how PT Dev Utility simplifies your Python development workflow
🚀 Transform Your Code from Complex to Simple
PT Dev Utility eliminates boilerplate code and provides clean, professional solutions for common development tasks. See the dramatic difference below:
📅 Time Operations
❌ Before: Complex Date Handling
import datetime
from dateutil.relativedelta import relativedelta
# Getting current date components - messy and error-prone
def get_date_parts():
now = datetime.datetime.now()
date_str = now.strftime('%Y_%m_%d')
parts = date_str.split('_')
return {
'year': parts[0],
'month': parts[1],
'day': parts[2]
}
# Getting timestamps - inconsistent formatting
def get_timestamp():
return datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
# Month calculations - complex and bug-prone
def get_previous_month():
now = datetime.datetime.now()
prev_month = now - relativedelta(months=1)
return prev_month.strftime("%Y_%m")
# IST timezone - manual offset calculations
def get_ist_time():
utc_now = datetime.datetime.utcnow()
ist_offset = datetime.timedelta(hours=5, minutes=30)
ist_time = utc_now + ist_offset
return ist_time.replace(microsecond=0).isoformat() + '+05:30'
✅ After: Clean & Simple with PT Dev Utility
import pt_dev_utility as pdu
# Getting current date components - one line!
date_parts = pdu.get_current_date_components()
# Getting timestamps - consistent and clean
timestamp = pdu.get_current_timestamp()
# Month calculations - simple and reliable
previous_month = pdu.get_month_year_string(1)
# IST timezone - handled automatically
ist_time = pdu.get_iso_timestamp_ist()
Result: 25+ lines reduced to 4 lines with better reliability!
📊 CSV Processing
❌ Before: Manual CSV Handling
import csv
import pandas as pd
# Reading CSV with custom headers - verbose and error-prone
def read_csv_custom(file_path, headers=None, columns=None):
try:
if headers:
df = pd.read_csv(file_path, header=None, names=headers, skiprows=1)
else:
df = pd.read_csv(file_path)
if columns:
df = df[columns]
result = []
for _, row in df.iterrows():
row_dict = {}
for col in df.columns:
row_dict[col] = row[col]
result.append(row_dict)
return result
except FileNotFoundError:
raise Exception(f"File not found: {file_path}")
except Exception as e:
raise Exception(f"Error reading CSV: {e}")
# Converting to SQL-like records - manual conversion
def csv_to_records(file_path):
try:
df = pd.read_csv(file_path)
records = []
for _, row in df.iterrows():
record_tuple = tuple(row.values)
records.append(record_tuple)
return records
except Exception as e:
raise Exception(f"Failed to convert CSV: {e}")
✅ After: Elegant CSV Operations
import pt_dev_utility as pdu
# Reading CSV with custom headers - clean and flexible
data = pdu.read_csv_as_dict_list(
'data.csv',
custom_headers=['name', 'age', 'city'],
selected_columns=['name', 'age']
)
# Converting to SQL-like records - one line!
records = pdu.load_csv_as_records('data.csv')
Result: 30+ lines reduced to 2 lines with better error handling!
⏱️ Performance Monitoring
❌ Before: Manual Timing Code
import time
import functools
from datetime import datetime
# Manual timing decorator - complex and repetitive
def time_it(func):
@functools.wraps(func)
def wrapper(*args, **kwargs):
start_time = time.time()
result = func(*args, **kwargs)
end_time = time.time()
elapsed = end_time - start_time
hours = int(elapsed // 3600)
minutes = int((elapsed % 3600) // 60)
seconds = int(elapsed % 60)
print(f"Function {func.__name__} took {hours:02d}:{minutes:02d}:{seconds:02d}")
return result
return wrapper
# Usage - requires custom decorator for each project
@time_it
def slow_function():
time.sleep(2)
return "done"
✅ After: Professional Timing Made Easy
import pt_dev_utility as pdu
# Professional timing - ready to use!
@pdu.measure_execution_time
def slow_function():
time.sleep(2)
return "done"
Result: 15+ lines reduced to 1 decorator with professional formatting!
📱 Telegram Notifications
❌ Before: Manual API Integration
import requests
import json
# Manual Telegram integration - error-prone and verbose
def send_telegram_alert(token, chat_id, message):
url = f"https://api.telegram.org/bot{token}/sendMessage"
payload = {
"chat_id": chat_id,
"text": message,
"parse_mode": "HTML"
}
headers = {
"Content-Type": "application/json"
}
try:
response = requests.post(url, json=payload, headers=headers)
if response.status_code == 200:
return True, response.json()
else:
return False, response.text
except requests.RequestException as e:
return False, str(e)
except Exception as e:
return False, f"Unexpected error: {e}"
# Usage - complex error handling required
success, result = send_telegram_alert(
"your_token",
"@channel",
"<b>Alert!</b> System is down"
)
if success:
print("Message sent!")
else:
print(f"Failed: {result}")
✅ After: Simple & Reliable Notifications
import pt_dev_utility as pdu
# Clean, professional notification system
success, result = pdu.send_telegram_message(
token="your_token",
message="<b>Alert!</b> System is down",
chat_id="@channel"
)
if success:
print("Message sent!")
else:
print(f"Failed: {result}")
Result: 25+ lines reduced to 3 lines with better error handling!
