Fatal Python error: Py_Initialize: can’t initialize sys standard streams AttributeErro python3.5+pycharm ,不确定其他环境会不会报错。

from datetime import datetimewith open('C:\Users\hhh\Desktop\sample.txt', 'w') as f: f.write('今天是 ') f.write(datetime.now().strftime('%Y-%m-%d'))with open('C:\Users\hhh\Desktop\sample.txt', 'r') as f: s = f.read() print('open for read...') print(s)with open('C:\Users\hhh\Desktop\sample.txt', 'rb') as f: s = f.read() print('open as binary for read...') print(s)

发现包名io有问题，在这个报名下即使是一条简单的print（’hello’）语句都会报上述错误，于是将包名改hhh(随便一个包名)。
error2 将报名改后，又出现了如下报错
**with open(‘C:\Users\hhh\Desktop\sample.txt’, ‘w’) as f:
^
SyntaxError: (unicode error) ‘unicodeescape’ codec can’t decode bytes in position 2-3: truncated \UXXXXXXXX escape**
经过调试发现文件路径格式不对

C:\Users\hhh\Desktop\sample.txt

将上述路径改为

C:\\Users\hhh\Desktop\sample.txt

正确代码如下
为什么需要改成这样呢？是因为Python的字符串本身也用\转义，所以要特别注意，建议使用Python的r前缀，就不用考虑转义的问题了

from datetime import datetimewith open('C:\\Users\zhaorongrong\Desktop\sample.txt', 'w') as f: f.write('今天是 ') f.write(datetime.now().strftime('%Y-%m-%d'))with open('C:\\Users\zhaorongrong\Desktop\sample.txt', 'r') as f: s = f.read() print('open for read...') print(s)with open('C:\\Users\zhaorongrong\Desktop\sample.txt', 'rb') as f: s = f.read() print('open as binary for read...') print(s)

运行结果
open for read…
今天是 2018-04-04
open as binary for read…
