How to iterate over the pandas rows

[SriMekala]

Hi,
I want to iterate through the "Pandas DataFrame" rows and while the "last_day <=day_set".

Condition1: Iterate over the rows of the first column.
sub_condition: on each iteration, check and break the iteration if day_set<=days_last.

I use below code, but not complete,

Kindly someone help.

import pandas as pd
import csv
input=r'D:\PythonCodes\correctiofactordata.csv'
df=pd.read_csv(input)
increment=3
prev_day=0
day_set=5
days_last=df[-1:]['Days_elapsed']
for i, row in df.iterrows():    
        data_catch=df.loc[(df['Days_elapsed'] >= prev_day) & (df['Days_elapsed'] <= day_set)]
        if((data_catch.shape[0])>0):
            print('Enough data')
        else:
            print('not enough data')
        print(prev_day),print(day_set)
        prev_day+=5
        day_set+=5
    
        print('-------------------')      

input data:

I use below code, but not complete,

is not a good description of the problem at hand.

The code above gives

Error:
KeyError: 'Days_elapsed'

Please show error trackbacks.

You need to set the correct sep for df=pd.read_csv(input)

Just something to think about StackOverflow: How to iterate over rows in a DataFrame in Pandas? Don't.

There is no error if I run the same code,

I want to iterate over rows while below condition satisfies.
Condition: "day_set<=days_last"
