python可以玩的方向有很多,比如爬虫、预测分析、gui、自动化、图像处理、可视化等等,可能只需要十几行代码就能实现酷炫的功能。
因为python是动态脚本语言,所以代码逻辑比java要简要很多,实现同样的功能少写很多代码。而且python生态有众多的第三方工具库,把功能都封装在包里,只需要你调用接口,就能使用复杂的功能。
下面举几个简单好玩的脚本例子,初学者可以照着代码写写,能快速掌握python语法。
1、使用pil、matplotlib、numpy对模糊老照片进行修复
import numpy as np
import matplotlib.pyplot as plt
from pil import image
import os.path
img_path = e:\test.jpg
img = image.open(img_path)
img = np.asarray(img)
flat = img.flatten()
def get_histogram(image, bins):
histogram = np.zeros(bins)
for pixel in image:
histogram[pixel] += 1
return histogram
hist = get_histogram(flat, 256)
cs = np.cumsum(hist)
nj = (cs - cs.min()) * 255
n = cs.max() - cs.min()
cs = nj / n
cs = cs.astype('uint8')
img_new = cs[flat]
img_new = np.reshape(img_new, img.shape)
fig = plt.figure()
fig.set_figheight(15)
fig.set_figwidth(15)
fig.add_subplot(1, 2, 1)
plt.imshow(img, cmap='gray')
plt.title(image 'before' contrast adjustment)
fig.add_subplot(1, 2, 2)
plt.imshow(img_new, cmap='gray')
plt.title(image 'after' contrast adjustment)
filename = os.path.basename(img_path)
plt.show()
2、将文件批量压缩,使用zipfile库import os
import zipfile
from random import randrange
def zip_dir(path, zip_handler):
for root, dirs, files in os.walk(path):
for file in files:
zip_handler.write(os.path.join(root, file))
if __name__ == '__main__':
to_zip = input(
enter the name of the folder you want to zip
(n.b.: the folder name should not contain blank spaces)
>
)
to_zip = to_zip.strip() + /
zip_file_name = f'zip{randrange(0,10000)}.zip'
zip_file = zipfile.zipfile(zip_file_name, 'w', zipfile.zip_deflated)
zip_dir(to_zip, zip_file)
zip_file.close()
print(f'file saved as {zip_file_name}')
3、使用tkinter制作计算器guitkinter是python自带的gui库,适合初学者练手创建小软件
import tkinter as tk
root = tk.tk()
root.title(standard calculator)
root.resizable(0, 0)
e = tk.entry(root,
width=35,
bg='#f0ffff',
fg='black',
borderwidth=5,
justify='right',
font='calibri 15')
e.grid(row=0, column=0, columnspan=3, padx=12, pady=12)
def buttonclick(num):
temp = e.get(
)
e.delete(0, tk.end)
e.insert(0, temp + num)
def buttonclear():
e.delete(0, tk.end)
4、pdf转换为word文件使用pdf2docx库,可以将pdf文件转为word格式
from pdf2docx import converter
import os
import sys
pdf = input(enter the path to your file: )
assert os.path.exists(pdf), file not found at, +str(pdf)
f = open(pdf,'r+')
doc_name_choice = input(do you want to give a custom name to your file ?(y/n))
if(doc_name_choice == 'y' or doc_name_choice == 'y'):
doc_name = input(enter the custom name : )+.docx
else:
pdf_name = os.path.basename(pdf)
doc_name =os.path.splitext(pdf_name)[0] + .docx
cv = converter(pdf)
path = os.path.dirname(pdf)
cv.convert(os.path.join(path, , doc_name) , start=0, end=none)
print(word doc created!)
cv.close()
5、python自动发送邮件使用smtplib和email库可以实现脚本发送邮件。
import smtplib
import email
from email.mime.text import mimetext
from email.mime.image import mimeimage
from email.mime.multipart import mimemultipart
from email.header import header
mail_host = smtp.163.com
mail_sender = ******@163.com
mail_license = ********
mail_receivers = [******@qq.com,******@outlook.com]
mm = mimemultipart('related')
subject_content = python邮件测试
mm[from] = sender_name
mm[to] = receiver_1_name,receiver_2_name
mm[subject] = header(subject_content,'utf-8')
body_content = 你好,这是一个测试邮件!
message_text = mimetext(body_content,plain,utf-8)
mm.attach(message_text)
image_data = open('a.jpg','rb')
message_image = mimeimage(image_data.read())
image_data.close()
mm.attach(message_image)
atta = mimetext(open('sample.xlsx', 'rb').read(), 'base64', 'utf-8')
atta[content-disposition] = 'attachment; filename=sample.xlsx'
mm.attach(atta)
stp = smtplib.smtp()
stp.connect(mail_host, 25)
stp.set_debuglevel(1)
stp.login(mail_sender,mail_license)
stp.sendmail(mail_sender, mail_receivers, mm.as_string())
print(邮件发送成功)
stp.quit()
小结python还有很多好玩的小脚本,你可以根据自己的场景来编写,也可以使用现成的第三方库。
以上就是五个有趣的python脚本的详细内容。
