该脚本会将您的 JSON 数据转换为 CSV 文件。它接受?.json?一个文件作为输入并提供?.csv?该文件作为输出。
pip install jsonimport jsonif __name__ == '__main__':
try:
with open('input.json', 'r') as f:
data = json.loads(f.read())
output = ','.join([*data[0]])
for obj in data:
output += f'\n{obj["Name"]},{obj["age"]},{obj["birthyear"]}'
with open('output.csv', 'w') as f:
f.write(output)
except Exception as ex:
print(f'Error: {str(ex)}')这个简单的 Python 项目使用?random?和?string?包来生成给定长度的随机字符串。
import random
import string
total = string.ascii_letters + string.digits + string.punctuation
length = 16
password = "".join(random.sample(total, length))
print(password)
在您选择的文件夹中查找包含提供的字符串的文件。

print("Download Complete!!")要运行以下脚本，您必须打开终端进入脚本的根目录，并需要输入以下命令
python3 scrap-img.py它会询问您刚刚下载的 chrome 驱动程序路径以及您要从中下载图像的 URL。
此 python 脚本显示有关设备电池百分比的通知。
要运行此脚本，我们需要?通过运行以下命令来下载psutil、?py-notifier和?win10tost 。
1. psutil
> pip install psutil
2. pynotifier
> pip install py-notifier
3. win10toast
> pip install win10toast# pip install psutil
import psutil
battery = psutil.sensors_battery()
plugged = battery.power_plugged
percent = battery.percent
if percent <= 30 and plugged!=True:
# pip install py-notifier
# pip install win10toast
from pynotifier import Notification
Notification(
title="Battery Low",
description=str(percent) + "% Battery remain!!",
duration=5, # Duration in seconds
).send()
打开终端进入脚本文件的根目录并运行以下命令
python3 battery.py
该脚本以三种不同的方式打印您的年龄：?年、?月、?日
import time
from calendar import isleap
# judge the leap year
def judge_leap_year(year):
if isleap(year):
return True
else:
return False
# returns the number of days in each month

return 31
elif month in [4, 6, 9, 11]:
return 30
elif month == 2 and leap_year:
return 29
elif month == 2 and (not leap_year):
return 28

end_year = begin_year + year
# calculate the days
for y in range(begin_year, end_year):
if (judge_leap_year(y)):
day = day + 366
else:
day = day + 365
leap_year = judge_leap_year(localtime.tm_year)
for m in range(1, localtime.tm_mon):
day = day + month_days(m, leap_year)
day = day + localtime.tm_mday
print("%s's age is %d years or " % (name, year), end="")
print("%d months or %d days" % (month, day))执行脚本非常简单！
只需在包含脚本的文件夹中打开终端并输入以下命令：
python3 calculate.py然后你必须输入姓名和年龄
input your name: XYZ
input your age: 33
Output - XYZ's age is 33 years or 406 months or 12328 days这是一个 Python 脚本，可根据扩展名将下载目录中的文件分类到其他文件夹中。

该项目包括一个简单的批量电子邮件脚本，可将相同的消息传递给收件人列表。
该项目仅需要 Python 标准库（更具体地说，是?csv、?email和?smtplib?模块）。
import csv
from email.message import EmailMessage
import smtplib
def get_credentials(filepath):
with open("credentials.txt", "r") as f:
email_address = f.readline()
email_pass = f.readline()
return (email_address, email_pass)
def login(email_address, email_pass, s):
s.ehlo()
# start TLS for security
s.starttls()
s.ehlo()
# Authentication
s.login(email_address, email_pass)
print("login")
def send_mail():
s = smtplib.SMTP("smtp.gmail.com", 587)
email_address, email_pass = get_credentials("./credentials.txt")
login(email_address, email_pass, s)
# message to be sent
subject = "Welcome to Python"
body = """Python is an interpreted, high-level,
general-purpose programming language.\n
Created by Guido van Rossum and first released in 1991,
Python's design philosophy emphasizes code readability\n
with its notable use of significant whitespace"""
message = EmailMessage()
message.set_content(body)
message['Subject'] = subject
with open("emails.csv", newline="") as csvfile:
spamreader = csv.reader(csvfile, delimiter=" ", quotechar="|")
for email in spamreader:
s.send_message(email_address, email[0], message)
print("Send To " + email[0])
# terminating the session
s.quit()
print("sent")
if __name__ == "__main__":
send_mail()该脚本需要使用两个配置文件：
项目目录包含两个示例文件，您几乎肯定希望并需要更改它们。
一旦你准备好这些文件，你所要做的就是
python Send_emails.py
