2. 安裝
image
下面默認就好
image
image
3.安裝完之后可以在命令窗口中輸出python查詢安裝是否成功

4.環(huán)境變量配置
（1）使用快捷鍵windows+r诫钓，輸入sysdm.cpl姿染，敲擊回車進入。
image
（2）點擊高級般眉。選擇最底部的環(huán)境變量。
image
（3）在系統(tǒng)環(huán)境變量中點擊編輯潜支。
image
（4）定義一個變量名稱甸赃。點擊瀏覽文件。找到需要添加變量的軟件所在的路徑冗酿。D:\python\python.exe埠对；D:\python\Scripts

二、pycharm下載安裝
1. pycharm下載地址https://www.jetbrains.com/pycharm/download/#section=windows
第一個是專業(yè)版裁替，是收費的项玛，功能比較全
第二個是社區(qū)版，是免費的弱判，功能比較少

4. 接下來就可以正常使用pycharm
image
image
5.在settings中設(shè)置. File--->Settings
設(shè)置字體大小
image
設(shè)置背景色开伏，選好之后，不要忘記點擊OK哦遭商！
image
最終固灵，效果如下。字體適中劫流，背景色比較漂亮巫玻，而且不會傷害眼睛丛忆。哈哈，本人非常滿意大审！你也可以根據(jù)自身情況進行選擇啦蘸际！
image
需要什么庫，直接在終端使用pip3命令下載即可
image
至此徒扶，Python和Pycharm都已經(jīng)安裝好粮彤。
永久激活pycharm
step1:下載jar包： 此jar包的目的就是讓截獲截止時間并騙過pycharm;
step2:下載完畢后， 將其放入pycharm在你本地的安裝目錄bin下姜骡。并且修改兩個以 vmoptions為結(jié)尾的啟動文件如圖所示:
image
image
并且在兩個文件后追加
-javaagent:E:\software\PyCharm 2019.1\bin\JetbrainsCrack-2.6.10-release-enc.jar
注意：自己的安裝目錄
step3:重啟pycharm 如需激活碼导坟，可填寫

pip
安裝python包基本都是使用pip
pip --help
pip使用實例
搜索包;
$ pip search redis
安裝redis包;
$ pip install redis
安裝指定版本;
$ pip install redis==2.10.5
升級包;
$ pip install --upgrade pip
查看redis驅(qū)動信息;
$ pip show redis
卸載redis驅(qū)動;
$ pip uninstall redis
列出所有安裝包;
$ pip list
列出待更新包;
$ pip list --outdate
這里特別關(guān)注一下install命令，查看一下幫助：pip help install
$ pip help install
Usage:
pip install [options] [package-index-options] ...
pip install [options] -r [package-index-options] ...
pip install [options] [-e] ...
pip install [options] [-e] ...
pip install [options] ...
........
下面說幾個重要參數(shù)：
升級一個軟件包
$ pip install --upgrade pip
批量安裝軟件包圈澈，使用-r指定一個文本惫周，在文本中指定軟件包名稱，也可以指定軟件包版本康栈。
$ pip install -r requirements.txt
修改pip的鏡像地址递递。
$ pip install -i https://mirrors.aliyun.com/pypi/simple/ redis
由于某些不可抗因素，Python官方的包在國內(nèi)有時無法訪問或出現(xiàn)網(wǎng)絡(luò)不穩(wěn)定現(xiàn)象啥么。為了解決這個問題就需要將Pip中自帶的源地址修改為鏡像地址登舞。
目前收集的比較好的鏡像地址有：
http://pypi.douban.com/simple/
http://mirrors.aliyun.com/pypi/simple/
如果不適用加密方式訪問的話就需要指定信任此主機。
$ pip install --trusted-host mirrors.aliyun.com -i http://mirrors.aliyun.com/pypi/simple/ redis
PIP配置文件
另外悬荣，PIP支持配置文件pip.conf菠秒，可以創(chuàng)建在/etc/pip.conf，或者在~/.pip/pip.conf氯迂。
$ cat /etc/pip.conf
[global]
timeout = 60
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple/
更多的參數(shù)使用可以看pip help [command]践叠。
問題：在PyCharm寫代碼時，光標變粗了嚼蚀，并且按退格鍵會刪除編寫的內(nèi)容禁灼。
原因：光標進入了改寫狀態(tài)。
解決方法：按一下鼠標Insert鍵就好了驰坊。
