建立一个文件(c.txt),将以下内容存入到文件中。然后将该文件中的每个英文字母加密后写入到一个新文件(d.txt)。加密的方法是:将A变成B,B变成C,……,Y变成Z,Z变成A;a变成b,b变成c,……,y变成z,z变成a,其他字符不变化。
I say to you today, my friends.
And so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream.
加密,保存在新的文件里

with open("c.txt", "w") as file: # w只写方式。如果文件不存在,则新建;存在,则覆盖;a追加方式。如果文件不存在,则新建;存在,则打开继续操作 file.write("I say to you today, my friends.") # 写入数据 file.write("And so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream.") with open("d.txt", "w") as fd: with open("c.txt") as fc: # 默认“r” line = fc.readline() words = [] for letter in line: # 遍历字符 ascii = ord(letter) # 字符转ascii tni = int(ascii) # 小写a97-z122,大写A65-Z90 if tni >= 97 and tni < 122: tni += 1 elif tni == 122: tni = 97 elif tni >= 65 and tni < 90: tni += 1 elif tni == 90: tni = 65 char = chr(tni) # ascii转字符 words.append(char) encrypted = "".join(words) fd.write(encrypted)
