在Python中将文本值转换为模块类型

我正在尝试使用下面的代码查看这些库是否已经安装在python环境中。

import os
libraries=['pandas','paramico','fnmatch'] #list of libraries to be installed 
for i in libraries:
    print("Checking the library", i ," installation")
    try:
       import i
       print("module ", i ," is installed")
    except ModuleNotFoundError:
       print("module ", i, " is not installed")

数组值没有被转换为模块类型，所有的东西都显示没有安装，所以如何将文本值从数组转换为模块类型。
在上面的示例中，panda和paramico没有安装，但安装了fnmatch。

python-3.x

使用importlib.import_module：

import os
import importlib

libraries=['pandas','paramico','fnmatch'] #list of libraries to be installed 
for i in libraries:
    print("Checking the library", i ," installation")
    try:
       importlib.import_module(i)
       print("module ", i ," is installed")
    except ModuleNotFoundError:
       print("module ", i, " is not installed")

输出示例：

Checking the library pandas  installation
module  pandas  is installed
Checking the library paramico  installation
module  paramico  is not installed
Checking the library fnmatch  installation
module  fnmatch  is installed
