Question

我打开一个16mb的简单txt文件，以使用mplotlib显示图形。在IDLE中运行python文件需要7秒才能显示图表。在VS Code中，需要17秒。文件大小为55mb时，分别需要17秒和53秒。

为什么VS Code变慢，我如何获得与IDLE相似的速度？

代码：

import numpy as np
import matplotlib.pyplot as plt
import time as time

time, v_out, v_in = np.loadtxt('PS_SIM.txt', unpack=True, skiprows=1)

plt.plot(time, v_out, label="Vout")

#Set legends
plt.legend(loc=8)
plt.grid()
plt.xlabel("Time [s]")
plt.ylabel("V_out [V]")
plt.suptitle("V_out")

#Set scales
plt.ylim(0.95, 1.05)
plt.yticks(np.arange(0.95,1.05, step=0.01))
plt.xlim(0.0085, 0.010)

#Show plot
plt.show()

settings.json：

{
    "python.pythonPath": "C:\\Users\\<..>\\AppData\\Local\\Programs\\Python\\Python36-32\\python.exe"
}

task.json：

    "version": "2.0.0",
"tasks": [
    {
        "label": "build",
        "type": "shell",
        "command": "msbuild",
        "args": [
            // Ask msbuild to generate full paths for file names.
            "/property:GenerateFullPaths=true",
            "/t:build"
        ],
        "group": "build",
        "presentation": {
            // Reveal the output only if unrecognized errors occur.
            "reveal": "silent"
        },
        // Use the standard MS compiler pattern to detect errors, warnings and infos
        "problemMatcher": "$msCompile"
    }
]

launch.json：

 "version": "0.2.0",
"configurations": [
    {
        "name": "Python: Current File (Integrated Terminal)",
        "type": "python",
        "request": "launch", 
        "program": "${file}",
        "console": "integratedTerminal"
    },
...

Idle和VS Code在执行代码时可能使用不同的Python解释器。当您从像VS Code这样的IDE中运行Python程序时，它将使用您在该IDE设置中指定的解释器。我猜Idle使用的是标准Python解释器，因为它实际上不是IDE

VS Code运行Python x2-3的速度比IDLE慢
