Apply lambda error (TypeError: 'str' object is not callable)

Generic
1

Hi, I am trying to apply lambda function by assigning 1 when df['Adj Close']> df['x candle high'] but it showed error. Anyone know what is the problem please? 



df['signal']= df.apply(lambda x : x==1 if x['Adj Close']> x['x candle high'] else 0, axis=1)

TypeError: 'str' object is not callable

Please see attachment if you need. 



Thanks in advance

the link to your code file does not seem to be accessible. Did you mean the following?



df['signal']= df.apply(lambda x : 1 if x['Adj Close']> x['x candle high'] else 0, axis=1)



Note: this requires the column names 'Adj Close' and 'x candle high' to be present and be numbers (or objects with comparison operators defined)
