I'm trying to iterate through a dataframe using iterrows and pull out two columns values. The index is a date/timestamp.
If the two columns are signal
and value
, I try:
for row in df_train.iterrows():
for value in row:
print(value['signal'])
I get the following traceback:
Traceback (most recent call last):
File "<ipython-input-148-34d711ac79ad>", line 3, in <module>
print(value['RSI_20'])
TypeError: 'Timestamp' object is not subscriptable
The iterrows
method actually yields two values: the index and the values of the row. So you should do:
for ts, row in df_train.iterrows():
print(ts, row['signal'], row['value'])
