+Using the Python language, have the function CaesarCipher(str,num) take the str
+parameter and perform a Caesar Cipher shift on it using the num parameter as the
+shifting number. A Caesar Cipher works by shifting each letter in the string N
+ places down in the alphabet (in this case N will be num). Punctuation, spaces,
+  and capitalization should remain intact. For example if the string is "Caesar
+   Cipher" and num is 2 the output should be "Ecguct Ekrjgt".
+"""
+# Input = "Hello" & num = 4Output = "Lipps"
+# Input = "abc" & num = 0Output = "abc"
