(PYTHON) What is wrong with my code, and why isnt it printing properly? It's supposed to be automated testing of functions that reverse Strings.

MY CODE

def strReverseI(s): '''(str) -> str

Iterative function to reverse s; return the reversed string.

Testing: Basic - 'abc', 'hello' Boundary - '' Equivalence classes - alpha, non-alpha

>>> strReverseI('abc') 'cba' >>> strReverseI('hello') 'olleh' >>> strReverseI('') '' >>> strReverseI('CIS 210') '012 SIC' ''' rstr = '' for ch in s: rstr = ch + rstr

return rstr

def strReverseR(word): ''' Reversing String ''' if(word==""): return word else: return strReverseR(word[1:])+word[0]

def test_reverse(functionName): ''' one parameter, f, a function (either strReverseR or strReversel) compares result returned by the called function to the expected result '''

#Set of test cases testCases = ((","),('a','a'),('xyz','zyx'),('testing123','321gnitet'),('hello, world','dlrow ,olleh'));

#Iterating over each pair for test in testCases:

#Calling functions by passing arguments functResult = functionName(test[0]);

#Comparing results if(functResult == test[1]): #If it passes the test print(" Checking(%'s)... it's value %s is correct! " %(test[0], test[1])); else: #If it fails to pass the test print(" Checking(%s)...Error: has wrong value %s, expected %s. " %(test[0], functResult, test[1]));

WHAT IT SHOULD BE PRINTING:

>>>def strReverseI (word): Reversing string # string that hold3 reve r 3e revStr = ""; # Iterating over 3tring in reve r 3e direction for i in range (len (word) -1, 1,-1) # Appending char by char revStr word [1] ; # Returning reverse 3tring return revStr >>>test reverse (strReverseR) Checking) its value is correct! Checking (a) its value a is correct! Checking (xyz) its value zyx is correct! Checking (testing123) its value 321gnitset is correct! Checking (hello, world) . .. its value dlrow,olleh is correct! >>>test reverse (strReverseI) Checking) its value is correct! Checking (a) its value a is correct! Checking (xyz) its value zyx is correct! Checking (testing123) its value 321gnitset is correct! Checking (hello, world) . .. its value dlrow,olleh is correct
