$\begin{gathered}\: \bigstar\:\: \:\underline {\red {\pmb{\mathbb{ REQUIRED \:\:PYTHON \:\:PROGRAM \::\:}}}}\:\\\\\end{gathered}$

$\begin{gathered}\qquad \tt{ \:num\:=\:float\: (\:input\:(\:\red{"\:Enter\: a \;number\::\: "}\:)\:)}\\ \qquad \tt{\:\blue{ if}\: num \: > \: 0\::\:}\\\qquad \qquad \tt{ print\:(\:\red{"\:The \:Entered\:number \:is \:Positive \:number\:"}\:)\:}\\ \qquad \tt{\:\blue{ elif}\: num \:==\: 0\::\:}\\\qquad \qquad \tt{ print\:(\:\red{"\:The\:Entered\:number \:is\:zero\:"}\:)\:}\\\qquad \tt{\:\blue{ else}\: num \::\:}\\\qquad \qquad \tt{ print\:(\:\red{"\:The\:Entered\:number \:is\:negative \:number\:"}\:)\:}\\\\\end{gathered}$
