Can you not just send the slice?

def R1(df):
if df['OPEN']>df['CLOSE']:
return "BEARISH"
elif df['OPEN']<df['CLOSE']:
return "BULLISH"
day1['type analysis'] = df.apply(R1,axis=1)the above code is what i trying to achieve.when the columns ['OPEN'] & ['CLOSE'] are in the same dataframe (df) i could pass it to the function as a whole dataframe and inside the function i can take necessary column and do the calculations. I was trying to figure out if there is a means to pass the only desired columns from two different dataframes into the function.
df.apply helps me to pass the whole dataframe, likewise can i pass two columns of two different dataframe (df1 & df2) to the function, and store the returned value to another dataframe (df3)

I presume you are working on some sort of stock market analysis, regarding if the market will be a good trading day or bad, (i.e. forecasting bears and bulls daily) through a bearish or bullish record. The only way I did it manually without a direct feed from the market was to put in a record of the Dow.
The "sum" was useful in the list.
while True:
df1 = int(float(input("Enter the opening of DOW Jones markets: ")))
df2 = int(float(input("Enter the closing of DOW Jones markets: ")))
OPEN = [0,0,df1]
CLOSE = [0,0,df2]
if (sum(OPEN))>(sum(CLOSE)):
print((sum(OPEN))-(sum(CLOSE)), 'OPENING')
print(('BEARISH'))
elif (sum(OPEN))<(sum(CLOSE)):
print((sum(OPEN))+(sum(CLOSE)), 'CLOSING')
print(('BULLISH'))
else:
print('Dow Jones Unchanged')
