What does ">>>" do in Python?

Question

The fuction of ">>>" in Python

Answer 1

'>>>' does nothing in Python, meaning that's not an operator.
Usualy, you're encountered it as the 'prompt' sign of Python Idle ( command line interpretor ). He's often reproduce in example on internet, and always start an instruction/line ;)

Complementary, '...' is the 'prompt' sign too in Idle, for new start line when the command/instruction needs multi lines ( and often indentation ).

Answer 2

Not at all...
In Python single line comments ( as '//' in C++ ) should start with '#', and multi-lines comments ( as '/* comment */ in C++ ) should be delimited by triple double quote ( """ comment """ ). This delimiters are also using for documentation/inline-help...

The '>>>' is rarely encoutered in a script, and if it does, it would be fortuitous... because it's be displayed as COMMAND LINE PROMPT, for the Python interpretor: a console/terminal like for directly executing Python instructions/code ^^

What isn't clear?

Answer 3

No, I couldn't: run a console/terminal whatever OS you have and type "python" ( if you have Python installed, in case of ms windows ) at the command prompt, obviously execute, and you will understand :|

Answer 4

This is my last answer:

If in the beginning of a line we have ">>>" it means that the example incite you to execute the nexted code directly at command line, but you can also write it in a file and say to python to run the file... Command line is a commodity to quickly and interactivly test an expression, or few lines of code. You never must type the triple '>', since it has a custom signification/reason...
