Python 3.x短版本的代码

Question

是否有更短的方法来检查字符串中的字符？谢谢：D

check = input("Put in the letter: ")
word = "word"

if(check == word[0]):
    print(check)
if(check == word[1]):
    print(check)
if(check == word[2]):
    print(check)
if(check == word[3]):
    print(check)

Answer 1

这个怎么样：

if check in word:
    print(check)

Answer 2

像

这样的东西

for l in word:
      if l == check:
            print (check)

也许？
