Other Important PyInputPlus Functions with Examples

Mastering Core PyInputPlus Functions:
-inputDate()
-inputYesNo()
-inputBool()
-inputEmail()
-inputFilepath()
-inputPassword()

PyInputPlus enhances Python's basic input() function by offering validated input prompts. This guide focuses on the most practical functions used in daily scripts and form validation.

inputDate(): Input and Validate Date

import pyinputplus as pyip
from datetime import datetime

date = pyip.inputDate("Enter your birth date (YYYY-MM-DD): ", formats=["%Y-%m-%d"])
print("Parsed date:", date)
print("Day:", date.day, "Month:", date.month, "Year:", date.year)

Explanation:

• Prompts the user for a date input and converts it into a datetime.date object.
• The formats argument accepts a list of valid input formats; here it expects exactly YYYY-MM-DD.
• If the input doesn't match the format or is invalid (e.g., month > 12), PyInputPlus re-prompts until valid or until limit/timeout if specified.

Sample Output (terminal):

Enter your birth date (YYYY-MM-DD): 2000-12-01
Parsed date: 2000-12-01
Day: 1 Month: 12 Year: 2000

inputYesNo(): Get a Yes/No Response

import pyinputplus as pyip

response = pyip.inputYesNo("Do you want to continue? ")
print("Response:", response)

Explanation:

• Accepts inputs: yes, no, y, or n, case-insensitively.
• Returns exactly "yes" or "no" (normalized to lowercase).
• If the user enters anything else, it shows a default error message and prompts again (unless limit/timeout/default used).

Sample Output (terminal):

Do you want to continue? y
Response: yes

inputBool(): Convert Yes/No to Boolean

import pyinputplus as pyip

confirm = pyip.inputBool("Do you accept the terms? ")
print("Accepted:", confirm)

Explanation:

• Uses the same valid entries as inputYesNo() (yes/no/y/n).
• Returns True if the user types yes/y, False if no/n.
• Ideal for binary decisions in code, so you can write: if pyip.inputBool(...): ...

Sample Output (terminal):

Do you accept the terms? no
Accepted: False

---

inputEmail(): Validate Email Format

import pyinputplus as pyip

email = pyip.inputEmail("Enter your email address: ")
print("Email:", email)

Explanation:

• Ensures the input is a syntactically correct email address (checks for pattern like user@domain.tld).
• Rejects inputs missing @, missing domain, or invalid characters.
• On invalid input, displays an error and re-prompts until valid (or until limit/timeout/default).

Sample Output (terminal):

Enter your email address: user@domain.com
Email: user@domain.com

---

inputFilepath(): Accept Valid File Paths

import pyinputplus as pyip

# exists=False means it only checks syntax, not actual existence
path = pyip.inputFilepath("Enter file path: ", exists=False)
print("Path entered:", path)

Explanation:

• Validates that the input follows valid file path syntax for the OS (e.g., correct use of separators).
• If exists=True is passed, it also checks that the file actually exists and re-prompts if not.
• Useful when you need to ensure user-specified paths meet requirements before opening files.

Sample Output (terminal):

Enter file path: C:\Users\Atul\Documents\log.txt
Path entered: C:\Users\Atul\Documents\log.txt

---

inputPassword(): Secure Hidden Input

import pyinputplus as pyip

pwd = pyip.inputPassword("Enter your password: ")
print("Password length:", len(pwd))

Explanation:

• Does not echo typed characters on the screen for security.
• Returns the entered password as a string, so you can compare or hash it afterward.
• If you want minimum length or other rules, combine with limit or custom validation in code.

Sample Output (terminal):

Enter your password: 
Password length: 8

📌 Common Date Format Specifiers for inputDate():

• %Y: Four-digit year (e.g., 2024)
• %m: Two-digit month (01–12)
• %d: Two-digit day of month (01–31)
• %b: Abbreviated month name (e.g., Jun)
• %B: Full month name (e.g., June)

These core PyInputPlus functions make handling validated user input simple, clean, and secure—perfect for command-line tools, automation scripts, and interactive Python applications.
