使用Python写入内容到制定文件

f=open('word.txt', 'a+')
# 以追加的方式打开文件
# 将信息写入文件
f.write("有时候你觉得特别难，也许因为有更大的收获')
f.close()
# 关闭文件

with open('book.txt','w', encoding='utf-8') as file:
	file.write('Python 实效编程百例'+'\n')
# 写入内容后换行就要加\n

with expression as target:
	with-body

print("\n","="*10,"Python经典应用","="*10)
with open('message.txt', 'w') as file:
# 创建或打开保存Python经典应用信息的文件
    pass
print("\n 即将显示..... \n")

import os

    with open('book.txt', 'r') as file:

else:
    file =open('book.txt')
    file.close()

    lines = file.read()
    if isinstance(lines, str):
        print(new)
    else:
        try:
