Python學習筆記之replace()

10-2 可使用方法replace()將字符串中的特定單詞都替換為另一個單詞。

讀取你剛創建的文件learning_python.txt 中的每一行，將其中的Python 都替換為另一門語言的名稱，如C。將修改后的各行都打印到屏幕上。

learning_python.txt文件內容如下：

In Python you can Handle file
In Python you can Automatic operation and maintenance
In Python you can make AI

 

編寫Python代碼：

filename='learning_python.txt'
with open(filename) as file_object:
    lines = file_object.readlines()
    for line in lines:
        print(line.replace('Python', 'C'))

 

執行結果：

In C you can Handle file

In C you can Automatic operation and maintenance

In C you can make AI
