Added a few more dummies for testing.
-# Dummy method for testing the str.isalnum() function
-def isalnum_test(s1):
+# Dummy method for testing adding a value
+def compare_op_dummy(x, y):
+ if x == y:
+ return 0
+ else:
+ return 1
+
+
+# Dummy method for testing the str.startswith method
+def startswith_dummy(s1, s2):
+ if s1.startswith(s2):
+ return 0
+ else:
+ return 1
+
+
+# Dummy method for testing the str.endswith method
+def endswith_dummy(s1, s2):
+ if s1.endswith(s2):
+ return 0
+ else:
+ return 1
+
+
+# Dummy method for testing the str.isalnum() method
+def isalnum_dummy(s1):
+ if not isinstance(s1, str):
+ return 2
if s1.isalnum():
return 0
else:
