提供两种读取方式,前者一次性读取文件,后者按行读取文件

# 一:一次性读取完
# def copy(filename, design):
#     f = open(filename, encoding='utf-8')
#     txt = f.read()
#     f.close()
#     with open(design, 'w', encoding='utf-8') as f:
#         f.write(txt)
#         print("success")

# 二,
# 逐行读取:
def copy(filename, design):
    f_1 = open(filename, 'r', encoding='utf-8')
    f_2 = open(design, 'w', encoding='utf-8')
    for line in f_1:
        f_2.write(line)
    f_1.close()
    f_2.close()

实现:
利用工具类将1.txt中的文字复制到untils_test.txt中:
