Hello, I saw the photo somewhere and I can't identify the font

Is monospaced type, look at the slashed zero from the line number gutter and the type of curly braces

“Somewhere” is not a proper source description. Please be more specific. 

Is from windows, Atom editor, monospaced font

The sample is small, but my bet is on BPmono [try it out] [more styles].

Thank you, yes that is, my friends also said that
