Say I have the following Excel file:
A B C
0 - - -
1 Start - -
2 3 2 4
3 7 8 4
4 11 2 17
df = pd.read_excel('your/path/filename')
This answer helps in finding the location of 'start' in the df
for row in range(df.shape[0]):
for col in range(df.shape[1]):
if df.iat[row,col] == 'start':
row_start = row
break
after having row_start you can use subframe of pandas
df_required = df.loc[row_start:]
And if you don't need the row containing 'start', just u increment row_start by 1
df_required = df.loc[row_start+1:]
