如何修复读取CSV文件时的内存错误?

我在读取CSV文件时出现了这个错误，有什么解决方案可以修复它吗? 我想从CSV文件得到电子邮件，但我得到这个错误一次又一次! 这是错误:

    Traceback (most recent call last):
      File "email-extractor.py", line 7, in <module>
        content = f.read()
    MemoryError

这是我的Python代码:

    import re

    fileInput = 'owner-emails.csv'
    fileOutput = 'email-gen-'+fileInput+'.txt'

    f = open(fileInput,encoding='utf-8')
    content = f.read()

    # email regex
    regex = re.compile(("([a-z0-9!#$%&'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+\/=?^_`"
                        "{|}~-]+)*(@|\sat\s)(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?(\.|"
                        "\sdot\s))+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)"))

    # set makes them unique
    results = set(regex.findall(content))

    emails = ""
    count = len(results)
    for x in results:
        emails += str(x[0])+"\n"

    # function to write file
    def writefile():
        f = open(fileOutput, 'w')
        f.write(emails)
        f.close()
        print("File written: " + fileOutput)

    writefile()
