大家好，我是讯享网，很高兴认识大家。

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 datetime with 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)

出现如下错误

Fatal Python error: Py_Initialize: can’t initialize sys standard streams
AttributeError: module ‘io’ has no attribute ‘OpenWrapper’

排查过程 error1

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

讯享网C:\Users\hhh\Desktop\sample.txt

将上述路径改为

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

讯享网from datetime import datetime with 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…
b’\xbd\xf1\xcc\xec\xca\xc7 2018-04-04’

Process finished with exit code 0

使用Python的r前缀，就不用考虑转义的问题了

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