25+ Python While Loop Questions and Answers:

1. Simple Countdown
Write a Python program that counts from 10 to 1 and print each number with the help of the while loop.

count = 10
while count > 0:
print(count)
count -= 1
print("Blast off!")

2. The sum of Positive Numbers

Create a Python while loop program that continuously asks the user for a positive number and keeps a running total. The loop must stop when the user enters a negative number.

total = 0
while True:
number = float(input("Enter a positive number (or a negative number to stop): "))
if number < 0:
break
total += number
print("Total sum of positive numbers:", total)

3. Password Validation

correct_password = "ProgrammingFunda@1"
user_input = ""

while user_input != correct_password:
user_input = input("Enter the password: ")
print("Access granted!")

4. Fibonacci Sequence

The Fibonacci Sequence in Python is one of the most asked questions during the Python interviews. I faced this question so many times in Python interviews.

Fibonacci Sequence:- The Fibonacci Sequence is a sequence of some numbers where one is the sum of two preceding numbers like 0, 1, 1, 2, 3, etc

Let’s write a Python code to generate the Fibonacci series in Python.

num = int(input("Enter a number:- "))

if num > 0:
i = 0
a = 0
b = 1
while i < num:
print(a, end=' ')
a, b = b, a + b
i = i + 1

PySpark RDD Actions with Examples ✅

===========================

What are PySpark RDD Actions?

PySpark RDD actions trigger the ex*****on of computations on the RDDs and return values to the driver program or write data to an external storage system.

PySpark RDD count():-

from pyspark.sql import SparkSession

spark = (

SparkSession.builder.appName("ProgrammingFunda.com")

.master("local[*]")

.getOrCreate()

)

sc = spark.sparkContext

key_value_dataset = [

("Math", 40),

("Physics", 71),

("Math", 60),

("English", 80),

("Chemistry", 75),

("English", 65),

("Physics", 62),

("Chemistry", 55),

("Social Science", 75),

("Math", 73),

]

rdd = sc.parallelize(key_value_dataset, 3)

print(rdd.count())

-------------------------------------------------

PySpark RDD first():-

from pyspark.sql import SparkSession

spark = (

SparkSession.builder.appName("ProgrammingFunda.com")

.master("local[*]")

.getOrCreate()

)

sc = spark.sparkContext

key_value_dataset = [

("Math", 40),

("Physics", 71),

("Math", 60),

("English", 80),

("Chemistry", 75),

("English", 65),

("Physics", 62),

("Chemistry", 55),

("Social Science", 75),

("Math", 73),

]

rdd = sc.parallelize(key_value_dataset, 3)

print(rdd.first())
