列表解析配合集合:通过遍历原列表并记录已出现元素,兼容所有Python版本。 seen = set() unique_list = [x for x in original_list if not (x in seen or seen.add(x))] 3. 第三方库方法 对于已安装pandas或numpy的场景,可直接调用封装好的方法: Pandas的drop_duplicates:适...
Example 1: Drop Duplicates from pandas DataFrame In this example, I’ll explain how to delete duplicate observations in a pandas DataFrame. For this task, we can use the drop_duplicates function as shown below: data_new1=data.copy()# Create duplicate of example datadata_new1=data_new1.dro...
Both duplicated and drop_duplicates default to consider all columns, but you can specify that they examine only a subset of columns in your DataFrame.Run this code in a cell:Python Copy example6.drop_duplicates(['letters']) Here's the output:...
data_new1=data.drop("x1",axis=1)# Apply drop() functionprint(data_new1)# Print updated DataFrame As shown in Table 2, the previous Python code has created a new pandas DataFrame with one column less, i.e. the variable x1 has been removed. ...
