This is a python program to find the Factorial of a number. num=int(input(“Enter a no to print it’s factorial:”)) fact=1 i=num while i>0: fact*=i i-=1 print(f”Factorial of {num} is {fact}”)   Factorial of a number n is (n)*(n-1)*(n-2)*(n-3)*……….*3*2*1.

A sequence starts from 0 and 1 and every next number is a sum of previous two number ,its known as Fibonacci  sequence or series. n=int(input(“Enter a number to print fabonacci series upto it:”)) a=0 b=1 print(a) print(b) c=0 while 1: c=a+b if c<n: print(c) a=b b=c  

This is a python program to print all the Prime Number in an interval. print(“To print all the prime numbers between a given interval”) a=int(input(“Enter first number:”)) b=int(input(“Enter second number:”)) l1=a+1 while l1<b: l2=2 temp=1 while l2<l1/2: if l1%l2==0: temp=0 if temp==1: print(l1)  

This is a python program to check given is a prime no or not. print(“Enter a number to be check whether it is prime or not :”) num=int(input()) Temp=0 i=2 while i<(num/2): if num%i==0: Temp=1 break i+=1 if Temp==1: print(f”{num} is not a prime number”) else: print(f”{num} is a prime number”)  

Python program to check Leap year. print(“Enter a year to be check whether it is leap year or not :”) y=int(input()) if y%4==0: print(“yes!this is a leap year”) else: print(“this is not a leap year”)  

This is a python program to check if a given number is odd or even . n=int(input(“Enter a number to be check whether it is even or odd :”)) if n%2==0: print(“Given number is even”) else: print(“Given number is odd”)  

print(“Enter a number to be check whether it is positive ,negative or zero:”) num=int(input()) if num==0: print(“number is zero”) elif num>0: print(“number is positive”) else: print(“number is negative”)  

To display calendar of a year here,we are using a calendar function and to display a particular month of a year ,we are using a month function from calendar module of python. #import the calender module import calendar print(“To display a calender of given month”) yy=int(input(“Enter a year”)) mm=int(input(“Enter a month to be display”)) print(calendar.month(yy,mm)) … Read more

This is a python program to convert temperature from Celsius  to Fahrenheit . print(“Temperature conversion”) print(“1.celcius to fehrenheit”, “2.fehrenheit to celcius”) choice=int(input(“Enter your choice”)) if choice==1: c=int(input(“Enter temperature in celcius”)) f=(9*c)/5+32 print(f”temperature in fehrenheit is {f}”) else: f = int(input(“Enter temperature in fehrenheit”)) c = ((f-32)*5)/9 print(f”temperature in celcius is {f}”)  

This is a python program to convert distance from kilometers to miles. print(” Distance conversion”) print(“1.kilometer to miles”, “2.miles to kilometer”) choice=int(input(“Enter your choice”)) if choice==1: d1=int(input(“Enter distance in kilometer”)) d2=d1*0.621371 print(f”Distance in miles is {d2}”) else: d1 = int(input(“Enter distance in miles”)) d2=d1/0.621371 print(f”Distance in kilometer is {d2}”)
