# Sample codes in Python

### Sum of three user input numbers

``````a=int(input("Enter first Number"))
b=int(input("Enter second Number"))
c=int(input("Enter third Number"))
sum=a+b+c
print(sum)``````

### Enter mark to get status of your division

`````` m=int(input("Enter your marks"))
if(m>=90):
print("You have Passed with First Distinction")

else:
if(m>=60):
print("You have passed with Second Distinction")
else:
if(m>=35):
print("You have just passed work hard next time")
else:
print("Failed")``````

### Factors of an input number

``````a=int(input("Enter A number"))
for x in range(1,a-1):
if(a%x==0):
print(x)``````

### Prime numbers upto an input value

``````a=int(input("Enter upto what value prime numbers are required: "))
b=0
for i in range(2,a):
b=0
for j in range(2,i):
if(i%j==0):
b=1
if(b<=0):
print(i)``````

### Factorial of an input number ( n! = 1*2*3 ... n )

``````a=int(input("Enter a number :"))
b=1
for i in range(1,a+1):
b=b*i
print("The factorial of the number is %d"%b)``````

### Fibonacci series upto a given number

``````n=10 # maximum value of the series
i=0
a=0
b=1
while(i<n):
next=a+b
a=b
b=next
print(next)
i=i+1``````

### Multiplication table upto 10

``````for i in range(1,10):
print("\n")
for j in range(1,10):
c=i*j
print("{:2d} ".format(c),end='')``````

### Sum of digits of an input number

``````a=int(input("Enter a Number :"))
sum=0
while(a>0):
i=a%10
sum=sum+i
a=a//10

print("sum of digits in number=%d"%sum)``````

### Check if input number is prime or not

``````a=int(input("Enter number :"))
for i in range(2,a):
if(a%i==0):
print("composite/Not a prime number")
break
else:
print("prime number")``````

### Converting Decimal to Binary number

``````def my_binary(n):
i=''
while n>1:
a = n%2
n = n//2
i=str(a)+i
i=  str(n%2) +i
print (i)

a=my_binary(156) ``````

### round a number without using round() function

``````x=float(input("input number "))
y=int(x+0.5)
print(y)``````
