Kickback -- find the first palindrome character in a group of characters

1. introduction
   This question is the first question of this week's buckle competition , We are learning to find palindromes python when , Will experience . Compared with the palindrome number , It would be easier to find palindrome characters

2. problem
   Here's an array of strings words, Find and return the first palindrome string in the array . If there is no string that meets the requirements , Returns an empty string ""
   List
   Input words = ["abc","car","ada","racecar","cool"]
   Output ："ada"

3. Method
   Build a function f(x), utilize for in Loop through character groups words Every character of , Then use the method of slicing to make the characters turn upside down , Reuse conditions if To determine whether the inverted character is equal to the original character , If you encounter the first equality , Then output the character and end the function , If there is no equal , Just go back to ””

4. Experimental results and discussion
   Through the experiment 、 Practice has proved that the proposed method is effective , Is able to solve the problem raised at the beginning .
   Code list

   def f(x): for i in x: d = i[::-1]: if d == i: return i return “” words = ["abc","car","ada","racecar","cool"] print(f(words))

5. Conclusion

Do this question , First of all, you need to know what palindrome characters are , And should have a certain understanding of slicing , In order to complete this problem faster . It should be noted that , Use for in loop , Have a certain understanding of the operation and stop of the cycle . Available functions for this problem , It's not necessary , But Li Kou has strict requirements for format , You must use functions to
