熊猫如何顺序检查列中的值

Question

I like to know how to check the int/float values in a column is sequential, eg in the following df , 2 of 3 columns are considered to have sequential values since their differences are 1;

inv_id   ven_id    pay_id
123      1.22      1230
124      2.22      1234
125      3.22      1235
126      4.22      1240
127      5.22      1241

inv_id and ven_id are sequential since the differences between values are all equal 1; pay_id is not sequential, since the differences between some of the values are 1.

Based on piRSquared's comment. You should first select only the numeric columns on your df:

numerics = ['int16', 'int32', 'int64', 'float16', 'float32', 'float64'] numeric_df = df.select_dtypes(include=numerics)

Then you should run:

numeric_df.diff().dropna().eq(1).all()
