TypeError：执行open（）时需要字符缓冲区对象 [英] TypeError: expected a character buffer object when doing open()

问题描述

所以我正在学习Python。我在用数组和open（）做简单的事情，有时这段代码行得通，有时却行不通！

So I'm learning Python. I was doing a simple thing with arrays and open(), and sometimes this code works, and sometimes it doesn't! Please help!

    print('Load? (Y/N)')
load = raw_input()
if load == "y":
    fin = open("myArr.bat", "r")
    myArr = fin.readline()
if load == "n":
    myArr = [0, 0, 0,
             0, 0, 0,
             0, 0, 0]
if load != "y" and load != "n":
    print 'WUT?'
    exit()

print (myArr[0]) ,  '|' ,  (myArr[1]) ,  '|' ,  (myArr [2])
print '----------'
print (myArr[3]) ,  '|' ,  (myArr[4]) ,  '|' ,  (myArr [5])
print '----------'
print (myArr[6]) ,  '|' ,  (myArr[7]) ,  '|' ,  (myArr [8])
print '_______________________________________________'
print 'What shall I change?'
print 'Number in array: '
foo = raw_input()
doo = int(float(foo))
print 'Number to change to: '
bar = raw_input()
dar = int(float(bar))
myArr[doo] = dar
print '_______________________________________________'
print (myArr[0]) ,  '|' ,  (myArr[1]) ,  '|' ,  (myArr [2])
print '----------'
print (myArr[3]) ,  '|' ,  (myArr[4]) ,  '|' ,  (myArr [5])
print '----------'
print (myArr[6]) ,  '|' ,  (myArr[7]) ,  '|' ,  (myArr [8])
fout = open("myArr.bat", "w")
fout.write(myArr)
fout.close()

它给了我这个：

   Traceback (most recent call last):
  File "Screen.py", line 35, in <module>
    fout.write(myArr)
TypeError: expected a character buffer object

推荐答案

这是因为 write 方法期望将字符串作为第一个参数，但是您正在将其传递给数组。

That's because the write method expects a string as the first argument, but you're passing it an array.
