为什么我不能删除 python 中的行？

Question

I am trying to delete the rows with missing values in python and the code runs but with no effect whatsoever. The rows are not deleted. I've added also a screenshot of my xls file.

This is how my code looks like:

  df = Pandas.read_excel('C:/Downloads/Report.xls')
  engine='python'
  new_df = df.dropna(inplace = true)
  puts new_df.to_string()

I've tried also with: new_df = df.dropna(axis=0, how="any", inplace=false) OR new_df = df.dropna()

IT DOES NOT DELETE THE ROWS.

I get the following result: Unnamed: 2 0 asset_number 1 WG0000000000 2 WG0000204381 3 WG0000204381 4 WG0000204381 5 WG0000204379 6 WG0000204379 7 WG0000204379 8 WG0000204366 9 WG0000204366 10 WG0000204366 11 WG0000204368...

Answer 1

First fill the empty rows with NaN and then delete the na value as following:

nan_value = float("NaN")
Convert NaN values to empty string
df.replace("", nan_value, inplace=True)
df.dropna(inplace=True)
print(df)
