Question

Please use the Python Language, preferabally 2.7, to solve this two probem set about while loops. The parameters and answer template for the solution is also given beneath the problem descriptions.

#PROBLEM 1
def removeOdd(l1):

    list1 = l1
    
#YOUR CODE GOES HERE (indented)

    return l1
    #END YOUR CODE

    
#PROBLEM 2
def getSecond(l1,l2):
    string1 = l1
    string2 = l2

    #YOUR CODE GOES HERE (indented)

    return string1
    #END YOUR CODE     

Problem 1: Write code to remove every odd number from a list. For example, the list [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] would yield [2, 4, 6, 8, 10].You may not use any built-in functions/methods besides len() and .append(). Problem 2: Write code that takes two strings from the user, and finds the index of the second string inside the first. For example, happybirthhappyday and happy yields the result 10. If the substring is not in the string more than once, your code should return -1.

Explanation / Answer

1.

def removeOdd(l1):

    list1 = l1
  
#YOUR CODE GOES HERE (indented)
    l1 = [] #making l1 empty
    i = 0 #variable to represent index in list
    while i < len(list1): #looping through entire list
      if list1[i] % 2 == 0: #if it is odd number
        l1.append(list1[i]) #appending to list
      i += 1 #incrementing index by 1
    return l1 #returning list
    #END YOUR CODE
print removeOdd([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])

output:

2.

def getSecond(l1,l2):
    string1 = l1
    string2 = l2
    index = -1
    #YOUR CODE GOES HERE (indented)
    n = len(string2) #finding length of string
    i = 0 #variable to represent index
    while i < len(string1)-(n-1): #looping though string1 and it should atleast contain n more charcters after i
      if string1[i:i+n] == string2: #if string is found
        index = i #updating index value
      i += 1 #incrementing index by 1
    return index
    #END YOUR CODE

s1 = raw_input("Enter first String")
s2 = raw_input("Enter second String")
print getSecond(s1,s2)

output:
