You will thank Python for this one day. +

Everything is Case-Sensitive

+ +

All names in Python are case-sensitive: variable names, function names, class names, module names, exception names. If you can get it, set it, call it, construct it, import it, or raise it, it’s case-sensitive. + +

+>>> an_integer = 1
+>>> an_integer
+1
+>>> AN_INTEGER
+Traceback (most recent call last):
+  File "<stdin>", line 1, in <module>
+NameError: name 'AN_INTEGER' is not defined
+>>> An_Integer
+Traceback (most recent call last):
+  File "<stdin>", line 1, in <module>
+NameError: name 'An_Integer' is not defined
+>>> an_inteGer
+Traceback (most recent call last):
+  File "<stdin>", line 1, in <module>
+NameError: name 'an_inteGer' is not defined
+
+ +

And so on. +
