A language is case-sensitive if it distinguishes between identifiers like myname and Myname. In other words, it cares about case- lowercase or uppercase. Let’s try this with Python.
>>> myname='Ramana'
>>> Myname
Traceback (most recent call last) :
File “<pyshell#3>”, line 1, in <module>
Myname
NameError : name ‘Myname’ is not defined
As you can see, this raised a NameError. This means that Python is indeed case-sensitive.
