To remove the multiple elements/items from the python list by index, you can use any above-mentioned methods, however, I will use the del keyword to explain. In order to use this you need a list of element indexes you wanted to remove and use it with for loop to remove iteratively. H...

2. Remove First Element from List Using pop() Method You can remove the first element from alistusing thepop()method in Python by passing an index0as argument to thepop()method. This will remove the first element from the list and return the element it removed. ...

When working with lists in Python, you may encounter scenarios when you need to remove multiple occurrences of items from a list. In such conditions, you will require a loop to iterate and remove the items. Using loop and remove()
These two options are likely to be the best solutions in most situations. However, there are other techniques to remove duplicates from a list. Using a loop to populate a new list A straightforward option is to iterate through the original list and add new items to a new list: ...
print(List) 输出 [1, 2, 3, 4, 5, 6] [1, 2, 10, 4, 5, 6] [1, 89, 78, 4, 5, 6] 还可以使用del关键字删除列表元素。如果我们不知道要从列表中删除哪个元素, Python还将为我们提供remove()方法。 请考虑以下示例, 以删除列表元素。
# Initialize empty list to store importancesimportances = [] # Iterate over all columns and remove one at a timefor i in range(X_train.shape[1]):X_temp = np.delete(X_train, i, axis=1)rf.fit(X_temp, y_train)acc = accuracy_scor...
