There exists yet another restriction on identifier names. The Python language reserves a small list of search phrases that designate Particular language functionality. No item can hold the exact same identify being a reserved word.
Equally as a literal price is usually displayed directly from the interpreter prompt in the REPL session with no require for print(), so can a variable:
There's nothing halting you from generating two distinct variables in the identical system known as age and Age, or for that matter agE. But it really might be ill-advised. It will surely be more likely to confuse any person attempting to read your code, and perhaps you on your own, after you’d been away from it awhile.

What comes about when it really is executed? Python would not generate A different item. It simply produces a different symbolic identify or reference, m, which details to exactly the same object that n points to.

Observe that scenario is significant. Lowercase and uppercase letters aren't exactly the same. Use of the underscore character is critical likewise. Just about every of the next defines a different variable:
The examples you've got viewed so far have utilized quick, terse variable names like m and n. But variable names is often extra verbose. Actually, it is normally useful When they are as it can make the purpose of the variable a lot more evident initially glance.
