AWS Cloud9 IDE to develop Python Programs

Learn to use AWS Cloud9 IDE to develop programs in Python language Objective: 1. Learn to use the AWS Cloud9 environment to create various python programs. Step 1: Create a Cloud9 environment. You can refer to our stepwise blog here for creating a Cloud9 environment. Follow step 1 to step 3.

Program 1: Write a program to Reverse a Number.

num = 12345 num_len = len(str(num))

while num_len>0: print(num_len, end = '')

num_len -= 1

Program 2. Write a program to check if the string is Palindrome or not. def isPalindrome(s):

return s == s[::-1] s = "radar" ans = isPalindrome(s)

if ans: print("String is Palindrome")

else: print("String is not Palindrome")

Program 3. Write a program to check if the number is prime number or not.

num = 14 if num == 1 or num == 2 or num ==3 or num == 5 or num == 7:

print(str(num)+" is Prime number.") elif ((num%3 ==0) or (num%5==0) or (num%7==0)):

print(str(num)+" is not Prime number.") else: print(str(num)+" is Prime number.")

Program 4. Write a program to print the maximum and minimum number from the list. a = [11, 23, 56, 34, 56, 67, 32, 43, 100] print("Greatest number from given list is: "+str(max(a)))

print("Smallest numberfrom given list is: "+str(min(a)))

Program 5. Write a python program to print the Fibonacci Series. n = int(input("Enter the value of 'n': "))

a = 0 b = 1 sum = 0 count = 1 print("Fibonacci Series: ", end = " ")

while (count <= n): print(sum, end = " ")

count += 1 a = b b = sum

sum = a + b

Program 6. Write a program to find Factorial of a given number. num = int(input("Enter a Number: "))

print("Factorial of ",str(num)," is: ", end = " ")

fact = 1 while num > 0:

fact *= num

num -= 1 print(fact)

Program 7. Write a program to find the Area of Circle. (Area of Circle = radius * radius * pi). from math import pi radius = int(input("Enter the radius of a circle: "))

area = radius * radius* pi print("Area of a circle is "+str('%.2f' %area))

Program 8. Write a program to swap numbers before the decimal and after. E.g., 567.897 would become 897.567 a = 567.897 a = str(a) b, c = a.split('.') print(c +'.'+b)

Program 9. Write a program to display the sum of odd and even digits in the number. E.g. for number 534726, sum of odd digits is 5+3+7=15 and even digits are 4+2+6=12 a = 534726 a = str(a)

e = 0 o= 0

for i in a: if int(i)%2 == 0:

e += int(i) else: o += int(i) print("Sum of odd digit is: "+str(o) +"\nSum of even digitis: ",str(e))

Program 10. Write a program to swap the two variables without using third variable. x = 10 y = 50 x, y = y, x

print("Value of x:", x)

print("Value of y:", y)

Note: If you no longer need the IDE, you may delete it.

DO YOU KNOW??

1. When Guido van Rossum began implementing Python, he was also reading the published scripts from “Monty Python’s Flying Circus”, a BBC comedy series from the 1970s. Van Rossum thought he needed a name that was short, unique, and slightly mysterious, so he decided to call the language Python.

2. There is actually a poem written by Tim Peters named "THE ZEN OF PYTHON"

which can be read by just writing import this in the interpreter.
