Error in defining the function

New to Julia

Hello
When I am trying to define the function and execute, I am getting the following error. Please help me in solving this

"
cannot define function f; it already has a value

Stacktrace:
[1] top-level scope
@ none:0
[2] top-level scope
@ In[18]:1
[3] eval
@ .\boot.jl:360 [inlined]
[4] include_string(mapexpr::typeof(REPL.softscope), mod::Module, code::String, filename::String)
@ Base .\loading.jl:1094

Your code probably creates a global variable f before defining the function. For example:

julia> f = 1
1

julia> f(x) = x
ERROR: cannot define function f; it already has a value
Stacktrace:
 [1] top-level scope at none:0
