i have a table in pandas df.

i want to change count to 1 wherever the count is Nan

df['count'] = 1

this would make all the columns to 1 but i dont want that, is there any way to define if condition in pandas df

you don't need a condition here, `fillna` will just do what you want – EdChum Nov 29 '16 at 12:47
`if not df[count]:df[count] = 1`? – Gábor Erdős Nov 29 '16 at 12:48
As @EdChum noted, this is a `fillna` question, just where you pass a value of `1` instead. – DSM Nov 29 '16 at 12:58
