在 pandas 中添加带有前缀的唯一标识符列
Adding unique identifier column with prefix in pandas
我正在尝试在 pandas DataFrame 中添加一个带有前缀“ACC”的唯一列。我该怎么做?
即
City New column,
Atlanta ACC-1,
Newyork ACC-2,
如果有唯一索引值使用:
df['New column'] = 'ACC-' + (df.index + 1).astype(str)
任何索引的另一个想法:
df['New column'] = np.arange(1, len(df) + 1)
df['New column'] = 'ACC-' + df['New column'].astype(str)
df['New column'] = [f'ACC-{i+1}' for i in range(len(df))]
