True/False Statement for a definition

MatthewRusso — Sat, 11 Dec 2021 12:47:11 GMT

Hi All,

I am trying to create a True Statement to check if a definition passed the "if"

On line 19 i am running "DEF RENAME" (Changes the name so the tool will run and I can fix it later)

Line 20 I want to know if Rename passed the if statement

My code is to change folders and shapefiles into a GDB while maintaining the structure of the folders. Please let me know if you have advice or see a large issue. The way I run this is through the command line.

def rename(variable):
    desc = arcpy.Describe(variable)
    name = desc.name
    new_name = "renamed"
    print name
    if " " or "-" or "0" or "1" or "2" or "3" or "4" or "5" or "6" or "7" or "8" or "9" in name:
        print("{0} is being changed to: {1}".format(name, new_name))
        arcpy.Rename_management(variable, new_name)
    else:
        pass

def import_to_GDB(input_workspace, output_workspace):
    import os
    base = os.path.basename(input_workspace)
    arcpy.CreateFileGDB_management(output_workspace, base)
    for dirpath, dirnames, filenames in arcpy.da.Walk(input_workspace):
        for dirname in dirnames:
            try:
                test = rename(dirname)
                if test == True:
                    dirname = "renamed"
                    dir_path = os.path.join(dirpath, dirname)
                    arcpy.env.workspace = dir_path
                    fcs = arcpy.ListFeatureClasses()
                    fds = os.path.join(output_workspace, base + ".gdb\\")
                    arcpy.CreateFeatureDataset_management(fds, dirname)
                    suboutput = os.path.join(fds, dirname)
                    count = 0
                else:
                    dir_path = os.path.join(dirpath, dirname)
                    arcpy.env.workspace = dir_path
                    fcs = arcpy.ListFeatureClasses()
                    fds = os.path.join(output_workspace, base + ".gdb\\")
                    arcpy.CreateFeatureDataset_management(fds, dirname)
                    suboutput = os.path.join(fds, dirname)
                    count = 0
            except:
                print("{0} had an error, passing to the next object".format(dirname))
            for fc in fcs:
                count = count + 1
                try:
                    arcpy.FeatureClassToGeodatabase_conversion(fc, suboutput)
                    print("{0} Complete".format(count))
                except:
                    print("{0} had an error, passing to the next object".format(fc))

Are you having an issue running this code or are you just looking for suggestions to improve your code that's already working?

This will give you some ideas

>>> name = 'bob1'
>>> nums = '0123456789- '
>>> vals = [i for i in nums]
>>> vals
['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '-', ' ']
>>> for i in vals:
...  print i, i in name
... 
0 False
1 True
2 False
3 False
4 False
5 False
6 False
7 False
8 False
9 False
- False
  False
>>>

Maybe it can't describe the name of a folder?

Sorry I wasn't clear, it is blowing up on me... here is the error:

Runtime error

Traceback (most recent call last):

This currently works, but it only tests for a "-" it was passing the if statment everytime if i tested " " .... any ideas?

You could make a list of things to check (checklist below), then find the matches between it and the name:

>>> name = 'john doe1'
>>> checklist = [' ','-','1','2','3','4']
>>> matches = [i for i in checklist if i in name]
>>> matches
[' ', '1']
