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 DataFrameIn 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 data data_new1 = data_new...
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. ...

Motivation: before this change column names were passed to DF ctor as arguments of LiteralString types (each name of it's own type), which seems to add to linear dependency of LLVM IR size and hence impact DF ctor compile time. Since this information is
