第11題,200內平方數是回文數的數字

1. for i in range(1, 201):
   
2.     print("", end=str(i) + "\n" if str(i * i) == str(i * i)[::-1] else "")
   
3.     #str[::-1]是反轉的意思(str[start:stop:step],從start退到stop ,並沒有甚麼不對2333),若 i * i == 反轉後的i * i,輸出i,否則空白
   

复制代码

1. for i in range(1, 201):
   
2.     a = list(str(i * i)) # i * i 轉成字串,再轉成列表
   
3.     b = list(str(i * i)) # 為了公平比較 ,一起轉
   
4.     a.reverse() # 反轉
   
5.     if a == b: # 若反轉前反相同,輸出
   
6.         print(i)

1. print("\n".join(str(i) for i in range(1, 201) if str(i * i) == str(i * i)[::-1])) # 列表生成式, 跟10同理

第12題,抽出文件中英文的詞語,並寫入

1. import re # 導入regex(叫正則表示式甚麼的)
   
2. 
   
3. file = open("from.txt", encoding='utf8').read() # 讀取檔案
   
4. output = open("to.txt", "w") # 生成寫入檔
   
5. 
   
6. fromList = re.findall(r"[a-zA-z]+", file) # 找出文檔中符合pattern的字,1 個或以上 a-z和A-Z
   
7. fromList.sort() # 排序
   
8. output.write("\n".join(fromList)) #寫入
