test = "TEAM_DEV_FTW_SOMETHING"

from that string I want the result to get Team Dev FTW从那个字符串我希望结果得到Team Dev FTW

What I tried so far:到目前为止我尝试过的：

team = " ".join(map(lambda x: x.capitalize(), test.name.split("_")[:3]))

Answer 1

Something like this?:像这样的东西？：

test = "TEAM_DEV_FTW_SOMETHING"
team = " ".join(map(lambda x: x.capitalize(), test.split("_")[:3]))
team = team[:-3] + team[-3:].upper()
print(team)

Answer 2

One way using enumerate :使用enumerate一种方法：

"_".join([i.upper() if n==2 else i.capitalize() 
          for n, i in enumerate(s.split("_")[:3])])

Output:输出：

'Team_Dev_FTW'
