Doubt in while loop.please explain

#1

in while loop:%d%i meaning?

#2

Hi @silpasweta,

print(" Step %d"%i)

%d basically means this is a placeholder for variable integer value, and after the statement we use %i to pass a int variable i to this placeholder

for eg:
initially i was 1

so it print Step 1, because %d will be replaced by i whose value is right now 1
in next iteration , i = 2, so %d will be replaced by 2 so, output is Step 2
similarly for all the iterations.

Some commons used types
%d is for integer
%s is for strings
%f is for float values

Thanks
