如何使用通配符在 DataFrame 中搜索特定字符串

Question

I have a DataFrame that has a column that I need to search using a wildcard. I tried this:

df = pd.read_excel('CHQ REG.xlsx',index=False)
df.sort_values(['CheckNumber'], inplace=True)
df[df.CheckNumber.str.match('888')]
df

This returns everything in by df

Here is my goal:

CheckBranch  CheckNumber
  Lebanon      8880121

Sample:

CheckBranch     CheckNumber
  Texas            4782436
  Georgia          8967462
  Lebanon          8880121
  China            8947512

Answer 1

Try:

res = df[df['CheckNumber'].astype('string').str.match('888')]
print(res)

Output

  CheckBranch  CheckNumber
2     Lebanon      8880121

As an alternative:

res = df[df['CheckNumber'].astype('string').str.startswith('888')]
