I want to get all value count in dataframe, so wrote this

counter = df.value_counts();
print(counter);

I expected this style

100.0   4
25.0    7
0.0     2
    .
    .

but it show me this, not value count.

Series([], dtype:int64)

What should I do to get value that I expected?

CodePudding user response：

IIUC, you can flatten the dataframe values and convert it to Series

out = pd.Series(df.values.flatten()).value_counts()
