Question

我试图用空白值替换电子表格中的单元格值N/A。

我尝试了各种在线上找到的replace格式。

if preferredphonenumber == 'N/A':
    replace = df1[rownum, 20].replace('N/A', 'blank', inplace=True, regex=True )
    print(replace)
else:
    print(df1)

我希望将N / A值替换为“空白”。

错误-

Traceback (most recent call last):
  File "C:\Python37\lib\site-packages\pandas\core\indexes\base.py", line 2890, in get_loc
    return self._engine.get_loc(key)

During handling of the above exception, another exception occurred:

如果要将所有具有“ N / A”的单元格替换为“”，则可以使用

df.replace("N/A","", regex=True, inplace=True)

如果仅要将一列中的“ N / A”替换为“”，则可以使用

df['Column_Name'].replace("N/A","", regex=True, inplace=True)

如果只想在一个特定的单元格中将“ N / A”替换为“”，则可以使用

df.at['X', 'Y'] = 10 
df.set_value('X', 'Y', 10)
#in both of the above cases you are technically assigning a new value to the cell, X is row , Y is column
