def file_write(file_name):
    f = open(file_name,'w')
    print('請輸入內容【單獨輸入\':w\'儲存退出】:')
    while True:
        write_some = input()
        if write_some != ':w':
            f.write('%s\n' %write_some)
        else:
            break
    f.close()
file_name = input('輸入檔名稱：\n')
file_write(file_name)

 

程式碼實現：

def file_compare(file_name_1,file_name_2):
    f_1 = open(file_name_1)
    f_2 = open(file_name_2)
    k1 = 0
    k2 = 0

    #lines_2 = f_2.readlines()
    for line_2 in f_2:
        lines_1 = f_1.readline()#readline和readlines!!
        if line_2 != lines_1:
            k1 += 1;
            print('第'+str(k1)+'行不一樣\n')

#for line_1 in lines_1
    print('共有'+str(k1)+'行不同\n')
        #line_1
    f_1.close()
    f_2.close()


file_name_1= input('輸入第一個需要比較的檔名稱：\n')
file_name_2= input('輸入第二個需要比較的檔名稱：\n')
file_compare(file_name_1,file_name_2)
