Drop row in pandas dataframe if any value in the row equals zero

Question

How do I drop a row if any of the values in the row equal zero?

I would normally use df.dropna() for NaN values but not sure how to do it with \"0\" values.

Answer 1

Assume a simple DataFrame as below:

df=pd.DataFrame([1,2,0,3,4,0,9])

Pick non-zero values which turns all zero values into nan and remove nan-values

df=df[df!=0].dropna()

df

Output:

    0
0   1.0
1   2.0
3   3.0
4   4.0
6   9.0

Answer 2

Although it is late, someone else might find it helpful. I had similar issue. But the following worked best for me.

df =pd.read_csv(r'your file')
df =df[df['your column name'] !=0]

Answer 3

i think the easiest way is looking at rows where all values are not equal to 0:

df[(df != 0).all(1)]

Answer 4

You could make a boolean frame and then use any:

>>> df = pd.DataFrame([[1,0,2],[1,2,3],[0,1,2],[4,5,6]])
>>> df
   0  1  2
0  1  0  2
1  1  2  3
2  0  1  2
3  4  5  6
>>> df == 0
       0      1      2
0  False   True  False
1  False  False  False
2   True  False  False
3  False  False  False
>>> df = df[~(df == 0).any(axis=1)]
>>> df
   0  1  2
1  1  2  3
3  4  5  6
