编解码器模块无法在文本文件中读取

Question

我有一个文本文件，希望逐行转换为base64。使用熊猫1.0.1和python 3.7我有一个文本文件，其中包含由回车符分隔的单词，名为sampleTEXT.txt熊猫可以读取文件，并且其中包含数据

import pandas as pd
words = pd.read_table("sampleTEXT.txt",names=['word'],encoding="utf-8",header=None)
words.head()
---      word
---------------
---0    difference
---1    where
---2    mc
---3    is
---4    the
---

下一个jupyter单元格具有此代码：

BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sampleTEXT.txt, "r", "utf-8") as sourceFile:
    with codecs.open(bsampleTEXT.b64, "w", "base64") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

但我收到此错误：

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-118-8aec7c80fc16> in <module>
      1 import codecs
      2 BLOCKSIZE = 1048576 # or some other, desired size in bytes
----> 3 with codecs.open(sampleTEXT.txt, "r", "utf-8") as sourceFile:
      4     with codecs.open(bsampleTEXT.b64, "w", "base64") as targetFile:
      5         while True:

NameError: name 'sampleACAD' is not defined

我知道文件在那里，这是可以的，因为熊猫可以将其作为数据框导入。我知道我使用的是here

中所述的正确语法

Answer 1

我有这个要工作：

import io,codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with io.open("sampleACAD.txt",mode="rb") as sourceFile:
    with codecs.open("bsampleACAD.b64", mode="w", encoding="base64") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

现在我只需要弄清楚如何将每个基数64个单词放在换行符上
