Basic Questions in Python.
#Basic questions in python
1) Write a program to take the number of kilometers as input and convert into meters and print the number of meters.
SOLUTION:
#taking kilometers as input of float data type
given_kilometers = float(input())
#converting kilometers to meters
meters = given_kilometers*1000
#printing the meters as output
print(int(meters))
INPUT: 1.2
OUTPUT: 1200
2.Write a program that reads a percentage P and prints the percentage P of the number 200.
#Taking input containing an integer.
a = int(input())
#Total value.
b = 200
#converting into percentage.
c = (a/100)*b
#printing the result as float in the output.
print(float(c))
INPUT: 50
OUTPUT: 100.0
3.Given a word W and an integer N, write a program to print the character present at the index N in the word W.
SOLUTION:
#Taking a word as first input.
word = input()
#Taking a number as second input.
number = int(input())
#indexing
index = word[number]
#printing index as output
print(index)
#Taking a word as first input.
word = input()
#Taking a number as second input.
number = int(input())
#indexing
index = word[number]
#printing index as output
print(index)
INPUT:
1.MOHAN
2. 2
OUTPUT:
H
4.Given a word and a number N, write a program to print the given word, N number of times in a single line.
SOLUTION:
#Taking a string as first input
string = input()
#Taking a number to repeat string as second input
number =int(input())
reapeated_string = string*number
#printing reapeated_string as output
print(reapeated_string)
INPUT:
1.Yashu
2. 3
OUTPUT:
YashuYashuYashu
5.Write a program to read a single line of input and print the first three characters in it.
SOLUTION:
#Taking a word as input
word = input()
#first three leters
final_word = word[:3]
#printing the output
print(final_word)
INPUT:
1.Four
OUTPUT:
Fou
6.Write a program that reads a word and prints the word excluding the fourth letter of the word.
SOLUTION:
word = input()
befor_letter = word[0:3]
fourth_letter = word[4:]
print(befor_letter + fourth_letter)
word=input()
length=len(word)
no_of_stars=length-4
first_two=word[:2]
last_two=word[length-2:]
middle_one="*"*no_of_stars
print(first_two+middle_one+last_two)
8.Write a program that reads two numbers A and B, and checks if both A and B are greater than 35 or A is greater than B.
SOLUTION:
number=input()
number=int(number)
number2=input()
number2=int(number2)
first=(number > 35) and (number2 > 35) or (number)>(number2)
print(first)
9.Write a program that reads two numbers A and B, and checks if both A and B are positive numbers or both A and B are less than 70.
SOLUTION:
first_num = input()
first_num = int(first_num)
second_num = input()
second_num = int(second_num)
positive = (first_num > 0) and (second_num > 0)
less = (first_num < 70) and (second_num < 70)
result = positive or less
print(result)
INPUT:
1.200
2.50
OUTPUT:
True
10.Write a program that reads three numbers A, B, and C, and checks if the sum of any two numbers is always greater than 10.
SOLUTION:
num1=int(input())
num2=int(input())
num3=int(input())
first=(num1+num2)>10
second=(num2+num3)>10
third=(num3+num1)>10
print(first and second and third)
11.Write a program that reads a three-digit number and checks if all the digits of the number are the same.
SOLUTION:
number = input()
first_digit = number[0]
second_digit = number[1]
third_digit = number[2]
result = first_digit == second_digit == third_digit
print(result)
first_number = int(input())
second_number = int(input())
if first_number > second_number:
print(first_number)
else:print(second_number)
