我正在阅读的所有内容都说email.MIMEMultipart包含在Python的基本库中，但在尝试运行需要它的代码时，我收到的消息是：
ModuleNotFoundError: No module named 'email.MIMEMultipart'
我在这里缺少一些简单的东西，或者由于某些原因我没有这个模块吗？
import sys
import time
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
答案 0 :(得分：0)
MIMEMultipart不是模块;它是#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <vector>
#include <iterator>
#include <algorithm>
using namespace std;
const string records_file("records.txt");
// declaring a struct for each record
struct record
{
int number; // number of record
vector<int> content; // content of record
};
// declaring an input operator to read a single record from a stream
istream& operator>>(istream &in, record &out)
{
out.number = 0;
out.content.clear();
string line;
if (getline(in, line))
{
istringstream iss(line);
if (iss >> out.number) {
cout << out.number << " ";
out.content.reserve(32); // WE KNOW THERE WILL BE 32 ENTRIES
copy(istream_iterator<int>(iss), istream_iterator<int>(), back_inserter(out.content));
for (int d = 0; d < out.content.size(); d++)
cout << out.content[d] << " ";
}
}
return in;
}
int main()
{
vector<record> batch_1; // stores integers from 1 - 64
vector<record> batch_2; // stores integers from 65 - 128
record temp;
// read the data file
ifstream read_records(records_file.c_str());
if (!read_records)
{
cerr << "Cannot open " << records_file << endl;
exit(EXIT_FAILURE);
}
cout << "Reading data file: " << records_file << endl;
while (read_records >> temp)
{
switch (temp.number)
{
case 1:
batch_1.push_back(temp);
break;
case 2:
batch_2.push_back(temp);
break;
}
}
read_records.close();
// process batch_1 and batch_2 as needed...
return 0;
}
模块中的一个类。要导入它，您必须：
email.mime.multipart
