在上述代码中,我们使用字典的方式创建了一个DataFrame对象,其中包含了两列数据:‘Name’和’Age’。 接下来,我们使用add_column方法向DataFrame中添加一列数据,例如添加一个’Gender’列,并赋予相应的值: df.add_column('Gender',['Male','Male','Female']) 1. 运行上述代码后,DataFrame中就会多出一个’Gender...
Example 1: Append New Variable to pandas DataFrame Using assign() Function Example 1 illustrates how to join a new column to a pandas DataFrame using the assign function in Python. Have a look at the Python syntax below: data_new1=data.assign(new_col=new_col)# Add new columnprint(data_...
Using a dog dataset, let's say you want to add a new column to your DataFrame that has each dog's height in meters instead of centimeters. On the left-hand side of the equals, you use square brackets with the name of the new column you want to create, in this case, height_m. ...
