Python – How to iterate over rows in a DataFrame in Pandas

dataframepandaspython

I have a DataFrame from Pandas:

import pandas as pd
inp = [{'c1':10, 'c2':100}, {'c1':11,'c2':110}, {'c1':12,'c2':120}]
df = pd.DataFrame(inp)
print df

Output:

   c1   c2
0  10  100
1  11  110
2  12  120

Now I want to iterate over the rows of this frame. For every row I want to be able to access its elements (values in cells) by the name of the columns. For example:

for row in df.rows:
   print row['c1'], row['c2']

Is it possible to do that in Pandas?

I found this similar question. But it does not give me the answer I need. For example, it is suggested there to use:

for date, row in df.T.iteritems():

or

for row in df.iterrows():

But I do not understand what the row object is and how I can work with it.

Best Solution

DataFrame.iterrows is a generator which yields both the index and row (as a Series):

import pandas as pd

df = pd.DataFrame({'c1': [10, 11, 12], 'c2': [100, 110, 120]})

for index, row in df.iterrows():
    print(row['c1'], row['c2'])
10 100
11 110
12 120
