Question

In python, please help me fill in these functions given their limitations. Please use for loops.

def palindrome(x):

"""

For a given string, determine if the string is a palindrome. (The same forward and back)

Input: String of any size (including empty)

Return: Boolean (True if palindrome, False otherwise)

Limitation: You must use a loop. Only function allowed to be used is len (if needed). Cannot use "in" besides "for var in container"

"""

pass

def getCount(char, strng):

"""

Get the number of times a character appears in a string.

Input: A character (length 1) and a string of any length

Return: Number of times a character appears

Limitation: Only functions we have been taught in class. Must use a loop. Cannot use "in" besides "for var in container"

"""

string = input("What word do you want to use? >>")

char = input("What letter do you want the number of? >>")

for char in string:

if string[1:] == char

x+=1

def getIndex(char, strng):

"""

Gets the index of the character in the string

Input: Character of length 1 and a string of any length

Return: The first occurence of the character appearing in the string.

Return the length of the string if the character does not exist

Limitation: Only functions we have been taught in class. Must use a loop. Cannot use "in" besides "for var in container"

"""

pass

def areEqual(str1, str2):

"""

Determines if 2 strings are equal

Input: 2 strings of any length (Both can be different lengths)

Return: Boolean

Limitation: Must use a single loop, and only 1 return statement in the code. Cannot use "in" besides "for var in container"

"""

pass
