Babylonian Method
The function should receive a number and return floating point number. Obviously you should test your function, so create a main program that asks the user a value, calculates the square root and displays that.
def sqrt(n):
x=n/2
y=x+1
while(x!=y):
z=n/x
y=x
x=(x+z)/2
return x
ans=”y”
while (ans==”y”):
n = float(input(“Give me a number: “))
if (n==0):
print(“The square root of 0 is 0”)
elif (n<0):
print(“Error no square root for negative numbers.”)
else:
sqrta=sqrt(n)
print (“The square root of”,n,”is”,sqrta)
ans = str(input(“Do you want to try again? y/n: “))
if (ans==”n”):
print (“Have a nice day.”)
else:
print (“Options were y or n but whatever have a nice day.”)

Greatest Common Divisor
The function should receive two integers and return an integer.Obviously you should test your function, so create a main program that asks the user for two values, calculates the gcd and displays that.
def gcd(x,y):
if (x==y):
ans=x
else:
if(x>y):
ans=gcd((x-y),y)
else:
ans=gcd(x,(y-x))
return ans
x=int(input(“Give me the first number: “))
y=int(input(“Give me the second number: “))
agcd= gcd(x,y)
print(“the Greatest Common Divisor of “,x,” and “,y,” is: “,agcd)

Yo soy 196
Your jobs is to create a program that asks the user for two pieces of data:
- The lower bound of the sequence
- The upper bound of the sequence
Then you check the values from the lower bound (inclusive) to the upper bound (inclusive) and make a report of them. During the analysis of each number, if a Lychrel number is found it should be reported immediately with something like “Found a Lychrel number: 196″
