Remove extra space after you finish the string:
'col1':

'col1' :

Why are you adding a nan value?
This is creating a mixed type column. (floats and strings) is this intentional?

NaN is used for marking missing values in string (object) dtype columns too, so this is OK.

You don't need to specify n
the same thing can be achieved with:
df.head(3)
