subprocess.Popen(...)

python3 實現代碼: 備忘write 要使用bytes 在最後結果轉為str 顯示時才不會出現 b‘‘ 這樣的位元組顯示

import subprocess

obj = subprocess.Popen(["python3"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
obj.stdin.write(bytes(‘print(1)‘,encoding=‘utf-8‘))
# obj.stdin.write(‘print 2 \n ‘)
# obj.stdin.write(‘print 3 \n ‘)
# obj.stdin.write(‘print 4 \n ‘)
obj.stdin.close()

cmd_out = obj.stdout.read()
obj.stdout.close()
cmd_error = obj.stderr.read()
obj.stderr.close()

print(str(cmd_out,encoding=‘utf-8‘))
print(cmd_error)
