用 Python 在一個給定的字串中倒序單詞
我們獲得了一條字串,我們的目標是在字串中倒序所有單詞。我們可以使用 split 方法和 reversed 函式來實現輸出。我們來看一些示例測試用例。
Input: string = "I am a python programmer" Output: programmer python a am I
Input: string = "tutorialspoint is a educational website" Output: website educational a is tutorialspoint
讓我們遵循以下步驟來實現我們的目標。
演算法
1. Initialize the string. 2. Split the string on space and store the resultant list in a variable called words. 3. Reverse the list words using reversed function. 4. Convert the result to list. 5. Join the words using the join function and print it.
檢視上述演算法的程式碼。
示例
## initializing the string string = "I am a python programmer" ## splitting the string on space words = string.split() ## reversing the words using reversed() function words = list(reversed(words)) ## joining the words and printing print(" ".join(words))
輸出
如果你執行以上程式,你會得到以下輸出。
programmer python a am I
讓我們再次對不同的輸入執行該程式碼。
示例
## initializing the string string = "tutorialspoint is a educational website" ## splitting the string on space words = string.split() ## reversing the words using reversed() function words = list(reversed(words)) ## joining the words and printing print(" ".join(words))
輸出
如果你執行以上程式,你會得到以下輸出。
website educational a is tutorialspoint
結論
如果你對教程有疑問,請在評論部分說明。
