创建一个列表t，如果其中包含“t”，则只保存运动员的姓名。如果不包含字母“t”，则将运动员姓名保存到列表oth中

Question

athletes = [['Phelps', 'Lochte', 'Schooling', 'Ledecky', 'Franklin'], ['Felix', 'Bolt', 'Gardner', 'Eaton'], ['Biles', 'Douglas', 'Hamm', 'Raisman', 'Mikulak', 'Dalton']]

t = [] 
other = []

for lst in athletes:
    for lst2 in athletes:
        if 't' in lst2:
            t.append(lst2)
        else:
            other.append(lst2)

Answer 1

# make a "flat" list of names
flat_list = sum(athletes, [])


# use list comprehensions
t = [x for x in flat_list if "t" in x]
other = [x for x in flat_list if "t" not in x]
