Python 2.7 搜寻及；使用Python逐行、逐字母替换表中的行

我使用python为ArcMap编写了一个脚本，该脚本将获取一个包含不受支持字符的表，将这些适用字段罗马化或音译，并创建一个包含表中可能包含的任何地理信息的shapefile。我确定的代码的其余部分工作正常。我的主要问题是能够在输入表的每一行中逐字搜索，这是我之前工作过的，但我想我回到了以前的错误

# Loop through each row in the copied table and replacing each cell with one based on the reference table.
rows = access.SearchCursor(outtable, orfield) # Creates a search cursor that looks in the outtable for what is in the native language field.
row = rows.next() # Establishes a variable that cycles row to row.

while row: # Beginning of "while" loop.
    for r in row: # Searches each letter within the searched row.
        for o in orfield: # Searches each cell based on the searched field from the reference table.
            if r == o: # If/Else statement for seeing if the letter being searched for in the intable (r) is identical to the letter in the orthography field (o).
                r.replace(orfield, profield) # Replaces any identical letters with the associated pronunciation.
            else:
                row.next() # Cycles to the next row.

我觉得我错过了什么，但不是很确定。如果您需要我详细说明我的脚本中还包含哪些内容，请告诉我。不一定需要为我编写脚本，但如果我可以为您编写一个模块或函数，请告诉我它是什么以及在哪里可以阅读它。

您的一些详细信息有点模糊，但代码似乎试图将字段数据对象（为行中的r创建的w/

）与某些输入集中的元素进行比较，你似乎暗示这是一个字符串。除了字段和字符串的类型不匹配之外，我认为行对象不适合您编写它的方式。您可以通过以下方式获取字段：

fldList = list()
for fld in arcpy.ListFields(r'C:\Workspace\somedata.shp'): 
    fldList.append(fld.name)

for fld in fldList:
     fldValue = row.getValue(fld)
     ....do some regex/string parsing
     ....if condition met, use row.setValue(fld, newValue) and rows.update(row)

然后使用如下方法迭代
fldList
：

fldList = list()
for fld in arcpy.ListFields(r'C:\Workspace\somedata.shp'): 
    fldList.append(fld.name)

for fld in fldList:
     fldValue = row.getValue(fld)
     ....do some regex/string parsing
     ....if condition met, use row.setValue(fld, newValue) and rows.update(row)
