我想从第一列打印 2 到 5 之间的值

Question

I want to print the value between 2 to 5 from 1first columns.

df5 = pd.DataFrame({
    'colA': ['C4GSP3JOIHJ2', 'CAGPS3JOIHJ2','CALCG3EST2','CLCCV3JOIHJ2','CLCNF3JOIHJ2','CLCQU3JOIHJ2','CLSMS3JOIHJ2','CMICO3JOIHJ2'],
    })

output look like this

Answer 1

df['output'] = df.colA.apply(lambda x: x[1:6]) 

should work. Docs for apply function: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.apply.html

Answer 2

df5['output']=df5['colA'].str[1:6]
