isLower is in base package. <br>
The tutorial has not spoken about importing modules.<br>
<br>
I use the IDE of fpcomplete.<br>

<div dir="ltr">isLower is not in the Prelude (the automatically
imported module built-in functions). Here's the list of all
functions in Prelude:

<div>isLower is in another module. You can figure that out by
searching for "isLower" on Hoogle:</div>
<div><a moz-do-not-send="true"
href="http://www.haskell.org/hoogle/">http://www.haskell.org/hoogle/</a><br>
</div>
<div><br>
</div>
<div>You can even find it by searching for it by type, which is
useful if you don't remember the precise name. Try searching
for "Char -> Bool".</div>
<div><br>
</div>
<div>In other words, you'll need to import isLower from
somewhere before you can use it.</div>

I try to selfstudy haskell by following the yet another
haskell tutorial.<br>
<br>
Now I have the exercise where I have a string and have to
convert it into a list of Booleans based on lower cats
letter using map.<br>
<br>
So i tried this<br>
<br>
x = "aBCde".islower:[]<br>
<br>
But I see this error : Not in Scope: 'isLower'.<br>
<br>
Where do I make my error.<br>
<br>
Do not give the answer otherwise I do not learn anything
from it.<br>
