如何在for循环中一次从2个不同的数据帧中读取行？

Question

I have 2 data frames: normal , cancer
and now I have a for loop to read them:

for line in normal,cancer():    
    if len(line) < 20:        
        print('Insufficient')      
        continue   

which means I want to read these 2 data by line at one time in a for loop.

How can I accomplish this?

Answer 1

Firstly, should cancer() be cancer ? Is it a function?

You could try doing a for lineNum, line in enumerate(normal) and then accessing cancer like cancer[lineNum]
