Python代码帮助

从键盘输入那个 直到*为止的那个，从键盘读写文件那个，来一个会写的

with open('data1.txt', 'w') as f:
    while 1:
        s = input("请输入:")
        if s == '*':
            break
        f.write(s+'\n')

with open('data1.txt', 'r') as f:
    for s in f.readlines():
        print(s[:-1])

print('请输入，按回车为一行')
with open('data1.txt', 'w') as f:
    while True:
        data = input()
        if '*' == data:
            break
        else:
            f.write(data + '\n')
with open('data1.txt') as f:
    for i in f.readlines():
        print(i, end='')

if name == 'main':
from sys import stdout
filename = 'data1.txt'
fp = open(filename,"w")
ch = input('输入字符串:\n')
while ch != '*':
fp.write(ch)
ch = input('输入字符串:\n')
ch = raw_input('')
fp.close()

with open('data1.txt','w') as f:
    while 1:
        str = input('请输入')
        if '*' not in str:
            # 按行写入数据
            f.writelines(str+'\n')
        else:
            break


with open('data1.txt','r') as f:
    #调用splitlines去除输出后的换行
    print(f.read().splitlines())

if name == 'main':
from sys import stdout
filename = 'data1.txt'
fp = open(filename,"w")
ch = input('输入字符串:\n')
