Or use:

或使用:

predictions[0].tolist()

Or can do something like:

或者可以执行以下操作:

'\n'.join(map(str,predictions[0].tolist()))

Or can do:

或者可以这样做:

for i in str(df).splitlines()[1:]:
    print(i.split(None,1)[1])

Or want to assign to string:

或者想分配给字符串:

s=''
for i in str(df).splitlines()[1:]:
    s+=i.split(None,1)[1]+'\n'
print(s.rstrip())

回答by Alexander

print(predictions.values.tolist())

Or

或者

df = pd.DataFrame(np.random.randn(5, 3), columns=list('ABC'))

>>> for row in df.values: print(row)
