Python：将 Excel 工作表从中文翻译成英文

Question

I am new to Python and I am trying to translate a Excel Sheet from Chinese to English. Id love to have a drag and drop field to load the Data Source but I am trying to get it to work first.

import sys
import pandas as pd
from googletrans import Translator 

# read from an excel file
df = pd.read_excel('TestBericht.xlsx')

# translate a column to English, and add back into the DataFrame
translator = Translator()         
df['transKunde'] = df['F9'].apply(translator.translate,src='zh-CN',dest='en').apply(getattr, args=('text',))

# output new excel file
df.to_excel('translatedFile.xlsx')

Now if I run the code it throws me a KeyError:

AppData\Local\Programs\Python\Python311\Lib\site-packages\pandas\core\indexes\base.py", line 3802, in get_loc
    return self._engine.get_loc(casted_key)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "pandas\_libs\index.pyx", line 138, in pandas._libs.index.IndexEngine.get_loc
  File "pandas\_libs\index.pyx", line 165, in pandas._libs.index.IndexEngine.get_loc
  File "pandas\_libs\hashtable_class_helper.pxi", line 5745, in pandas._libs.hashtable.PyObjectHashTable.get_item
  File "pandas\_libs\hashtable_class_helper.pxi", line 5753, in pandas._libs.hashtable.PyObjectHashTable.get_item
KeyError: 'F9'
Desktop\Uebersetzer.py", line 10, in <module>
    df['transKunde'] = df['F9'].apply(translator.translate,src='zh',dest='en').apply(getattr, args=('text',))
                       ~~^^^^^^
KeyError: 'F9'

I have been going through stackoverflow to find a solution but I didnt find anything. The Script I am referring to is from: Excel sheet translation using python

You can use df.iat[row, column] to access exactly the cells you need:

Access a single value for a row/column pair by integer position.

Similar to iloc , in that both provide integer-based lookups. Use iat if you only need to get or set a single value in a DataFrame or Series.

Remember that pandas take the first column and first row as the header/fields of the data. Pandas also uses 0 as the starting index, so your coordinate would be 9-2,F-2 -> [7,4] like so:

df['transKunde'] = df.iat[7,4].apply(translator.translate,src='zh-CN',dest='en').apply(getattr, args=('text',))
