Hi, I need to pass year to the path inside a for loop in python script. years = [ 2010 , 2011 , 2012 ] months = [ 9 ] for year in years : for month in months : arcpy . env . workspace = r 'H:\Test_ONLY\prism_800m_' + year [ : 4 ] scratch = r 'H:\Test_ONLY\scratch' if year % 4 > 0 and month == 9 : fmaskrasters1 = fmaskrasters [ 243 : 249 ] fmaskrasters2 = fmaskrasters [ 249 : 255 ] fmaskrasters3 = fmaskrasters [ 255 : 261 ] fmaskrasters4 = fmaskrasters [ 261 : 267 ] fmaskrasters5 = fmaskrasters [ 267 : 273 ] else : print ( "Not configured in the script!" ) I want to change r'H:\Test_ONLY\prism_800m_2010 each time for the months from Sep. How can I achieve this by modifying the above code. I think I am not doing something right in arcpy.env.workspace = r'H:\Test_ONLY\prism_800m_'+ year[:4] can somebody help me to correct this? Thanks in advance.

Hi Dimindu, Try the following: arcpy . env . workspace = r 'H:\Test_ONLY\prism_800m_' + str ( year )

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

I want to change r'H:\Test_ONLY\prism_800m_2010 each time for the months from Sep.

How can I achieve this by modifying the above code. I think I am not doing something right in arcpy.env.workspace = r'H:\Test_ONLY\prism_800m_'+ year[:4]

can somebody help me to correct this?

Thanks in advance.
