Python Pandas Dataframe, remove all rows where 'None' is the value in any column

Question

I have a large dataframe. When it was created \'None\' was used as the value where a number could not be calculated (instead of \'nan\')

How can I delete all rows that h

UPDATE:

In [70]: temp[temp.astype(str).ne('None').all(1)]
Out[70]:
      0     1  2  3  4  5   6  7
0  str1  str2  2  3  5  6  76  8

Old answer:

In [35]: x
Out[35]:
      a     b   c
0     1     2   3
1     4  None   6
2  None     7   8
3     9    10  11

In [36]: x = x[~x.astype(str).eq('None').any(1)]

In [37]: x
Out[37]:
   a   b   c
0  1   2   3
3  9  10  11

or bit nicer variant from @roganjosh:

In [47]: x = x[x.astype(str).ne('None').all(1)]

In [48]: x
Out[48]:
   a   b   c
0  1   2   3
3  9  10  11
