Calculator and file handling - 22/06/2026 09:53 EDT

I’d like a simple yet polished mobile calculator app written in Python. It must do the everyday basics—addition, subtraction, multiplication and division—and also offer a graph-plotting screen where I can enter a function such as y = 2x + 3 and see the curve render instantly.

Please build it as a true mobile application that runs on both Android and iOS. Kivy, BeeWare or any other Python-friendly framework is fine so long as I can open the project in a standard Python 3 environment, read the code and continue learning from it.

What I expect to receive
• Complete, well-commented source code
• A brief README with setup, build and deployment steps
• Debug or release builds that I can sideload for quick testing (APK for Android; TestFlight, IPA or simulator build for iOS)

Clean, readable code and a straightforward UI are more important than elaborate styling. If you already have ideas for making the graphing interface intuitive—pinch-zoom, pan, light/dark mode—feel free to suggest them.
rint("Calculator")

a = float(input("Pehla number: "))
op = input("Operator (+, -, *, /): ")
b = float(input("Dusra number: "))

if op == "+":
print("Answer =", a + b)
elif op == "-":
print("Answer =", a - b)
elif op == "*":
print("Answer =", a * b)
elif op == "/":
if b != 0:
print("Answer =", a / b)
else:
print("0 se divide nahi kar sakte")
else:
print("Galat operator")
Mobile App Calculator Kaise Banaye?
Python basics achhe se seekho.
Android Studio install karo.
Java ya Kotlin seekho.
Calculator ka UI banao (buttons aur display).
Addition, subtraction, multiplication aur division ka code likho.
Paise Kaise Kama Sakte Ho?
App ko Google Play Store par publish kar sakte ho.
Kisi dukaan, school ya chhote business ke liye app bana sakte ho.
Freelancing websites par clients ke liye apps bana sakte ho.

Abhi tum 17 saal ke ho aur Python seekh rahe ho, to pehle Python me calculator bana kar practice karo. Uske baad main tumhe GUI (window wala) calculator banana bhi sikha sakta hoon.

mujhe code ageya hai samjh kar ab tum mujhe ye betaome aap kese bheno hu aur freelanchig per kese bhechu

Agar tumhe Python ka basic code samajh aa gaya hai, to app banane aur freelancing shuru karne ka ek practical raasta ye ho sakta hai:

App Kaise Banao?
Python ke baad OOP aur File Handling acche se seekho.
GUI (window wali app) banana seekho:
Python me Tkinter
Ya mobile apps ke liye Flutter
Chhote projects banao:
Calculator
To-Do List
Student Management System
Expense Tracker
Har project ka screenshot aur code sambhal kar rakho.
Freelancing Par Kaise Becho?

Freelancing me log tumhe hire karte hain.

Popular platforms:

Fiverr
Upwork
Freelancer.com
Shuruaat Kaise Karo?
Account banao.
Apne projects upload karo.
Ek service likho:
"I will create a Python calculator app"
"I will build a simple student management system"
Shuru me kam rate rakho taaki pehle clients mil saken.
Achha kaam karke reviews lo.
Abhi Tumhari Priority

Freelancing se pehle kam se kam 5–10 projects bana lo. Jab koi client puche, to tumhare paas dikhane ke liye kaam hona chahiye.

print("Calculator")

a = float(input("Pehla number: "))
op = input("Operator (+, -, *, /): ")
b = float(input("Dusra number: "))

if op == "+":
print("Answer =", a + b)
elif op == "-":
print("Answer =", a - b)
elif op == "*":
print("Answer =", a * b)
elif op == "/":
if b != 0:
print("Answer =", a / b)
else:
print("0 se divide nahi kar sakte")
else:
print("Galat operator")
I am interested in your Mobile Calculator with Graphing project. I have programming knowledge and would like to discuss the project requirements. Please let me know what features you need and your expected timeline.
