Remove part of name of element in list-CodePudding

I have a list called l which contains the following elements:

['weight_Thomas', 'weight_Michael', 'weight_Donald', 'weight_Liam', 'weight_Ethan', .....]

I would like to change it to:

['Thomas', 'Michael', 'Donald', 'Liam', 'Ethan', .....]

so that only the names are in it without the string 'weight'.

CodePudding user response：

Try using map with split

list(map(lambda x: x.split("_")[1], l))

CodePudding user response：

Another solution just using list comprehension:

values = ['weight_Thomas', 'weight_Michael', 'weight_Donald', 'weight_Liam', 'weight_Ethan']

value_new = [l.split('_')[1] for l in values]

Output:

['Thomas', 'Michael', 'Donald', 'Liam', 'Ethan']

CodePudding user response：

assuming your list is called items

names_only = [item.split("_")[1] for item in items]

CodePudding user response：

let tempArr = ['weight_Thomas', 'weight_Michael', 'weight_Donald', 'weight_Liam', 'weight_Ethan'];

let changedArr = tempArr.map(e=>e.split('_')[1]);
console.log(changedArr)

can you try this?
