#python

于 2024-04-26 15:25:31 首次发布

1、安装

brew install python

2、配置 环境变量

·打开

 sudo vi ~/.bash_profile

·添加

export PATH="/opt/homebrew/bin:$PATH"

·重载

 source ~/.bash_profile 
  ✗ source ~/.zshrc             # 按需

3、验证

·方式 1

ls -l /opt/homebrew/bin/python3

·方式 2

echo $PATH

· 方式 3

/opt/homebrew/bin/python3 --version

4、shell 运行 python

/opt/homebrew/bin/python3 /path/to/your/script/demo.py

  • 方法 1
#!/bin/bash

# 定义函数
process_timestamp() {
  timestamp=$1
  formatted_date=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y-%m-%d %H'))")
  id=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y%m%d%H'))")

  echo "timestamp: $timestamp"
  echo "id: $id"
  echo "Formatted Date: $formatted_date"
}

# 获取当前时间，格式为 yyyy-MM-dd HH:mm:ss
current_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "当前时间：$current_time"

begin_timestamp=$(python3 -c "from datetime import datetime, timezone; print(int(datetime.now(timezone.utc).replace(minute=0, second=0, microsecond=0). timestamp()))")
begin_local_time=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($begin_timestamp).strftime('%Y-%m-%d %H'))")


echo "begin_timestamp: $begin_timestamp"
echo "begin_local_time: $begin_local_time"

for ((i=0; i<=3; i++)); do
  timestamp=$((begin_timestamp - 3600*i))
  process_timestamp $timestamp
done
  • 方法 2
#!/bin/bash

current_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "当前时间：$current_time"

begin_timestamp=$(python3 -c "from datetime import datetime, timezone; print(int(datetime.now(timezone.utc).replace(minute=0, second=0, microsecond=0). timestamp()))")
begin_local_time=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($begin_timestamp).strftime('%Y-%m-%d %H'))")

echo "begin_timestamp: $begin_timestamp"
echo "begin_local_time: $begin_local_time"

for ((i=0; i<=3; i++)); do

  timestamp=$((begin_timestamp - 3600*i))
  formatted_date=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp(int('$timestamp')).strftime('%Y-%m-%d %H'))")
  id=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp(int('$timestamp')).strftime('%Y%m%d%H'))")

  echo "timestamp: $timestamp"
  echo "id: $id"
  echo "Formatted Date: $formatted_date"
done

结果

当前时间：2024-04-26 19:04:50
begin_hour: 11
begin_utc_time: 2024-04-26 11
begin_timestamp: 1714100400
timestamp: 1714100400
id: 2024042611
Formatted Date: 2024-04-26 11
timestamp: 1714096800
id: 2024042610
Formatted Date: 2024-04-26 10
timestamp: 1714093200
id: 2024042609
Formatted Date: 2024-04-26 09
timestamp: 1714089600
id: 2024042608
Formatted Date: 2024-04-26 08

5、拓展

5.1、倒叙打印 小时、天、周、月 的开始和结束时间

5.1.0、批量执行脚本

#!/bin/bash

# 保存要执行的脚本文件名到一个数组中
scripts=(
  "datetest_hour.sh"
  "datetest_day.sh"
  "datetest_week.sh"
  "datetest_month.sh"
)

# 遍历脚本数组，逐个执行脚本
for script in "${scripts[@]}"
do
    echo "执行脚本: $script"
    bash "$script"
    echo "脚本执行完成: $script"
done

5.1.1、按小时打印开始和结束

#!/bin/bash

number=3
# 1小时
timeSeconds=3600

# 定义函数
process_timestamp() {
  timestamp=$1
  next_hour_timestamp=$((timestamp + $timeSeconds))
  timestampStr=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y-%m-%d %H'))")
  id=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y%m%d%H'))")
  dateIndex=$(python3 -c "from datetime import datetime, timezone; print(datetime.fromtimestamp($timestamp, timezone.utc).strftime('%Y-%m-%dT%H:%M:%SZ'))")
  current_utc_time=$(date -u +"%Y-%m-%dT%H:%M:%SZ")

  
  echo "id: $id"
  echo "timestampStr: $timestampStr"
  echo "timestamp(s)：$timestamp"
  echo "dateIndex: $dateIndex" 
  echo "next_hour_timestamp(s)：$next_hour_timestamp"
  echo "current_utc_time：$current_utc_time"
}

# 获取当前时间，格式为 yyyy-MM-dd HH:mm:ss
current_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "当前时间：$current_time"

begin_timestamp=$(python3 -c "from datetime import datetime, timezone; print(int(datetime.now(timezone.utc).replace(minute=0, second=0, microsecond=0). timestamp()))")
begin_local_time=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($begin_timestamp).strftime('%Y-%m-%d %H'))")


echo "begin_timestamp: $begin_timestamp"
echo "begin_local_time: $begin_local_time"

# 按小时循环-最近 n 个小时
for ((i=0; i<=$number; i++)); do
  timestamp=$((begin_timestamp - $timeSeconds*i))
  process_timestamp $timestamp
done

5.1.2、按天打印开始和结束

#!/bin/bash


number=3
# 1小时
timeSeconds=$((3600 * 24))

# 定义函数
process_timestamp() {
  timestamp=$1
  next_hour_timestamp=$((timestamp + $timeSeconds))
  timestampStr=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y-%m-%d'))")

  dateIndex=$(python3 -c "from datetime import datetime, timezone; print(datetime.fromtimestamp($timestamp, timezone.utc).strftime('%Y-%m-%dT%H:%M:%SZ'))")
  current_utc_time=$(date -u +"%Y-%m-%dT%H:%M:%SZ")

  
  echo "id: $id"
  echo "timestampStr: $timestampStr"
  echo "timestamp(s)：$timestamp"
  echo "dateIndex: $dateIndex" 
  echo "next_hour_timestamp(s)：$next_hour_timestamp"
  echo "current_utc_time：$current_utc_time"
}

# 获取当前时间，格式为 yyyy-MM-dd HH:mm:ss
current_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "当前时间：$current_time"

begin_timestamp=$(python3 -c "from datetime import datetime, timezone; print(int(datetime.now(timezone.utc).replace(hour=0, minute=0, second=0, microsecond=0).timestamp()))")
begin_local_time=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($begin_timestamp).strftime('%Y-%m-%d'))")


echo "begin_timestamp: $begin_timestamp"
echo "begin_local_time: $begin_local_time"

# 按小时循环-最近 n 个小时
for ((i=0; i<=$number; i++)); do
  timestamp=$((begin_timestamp - $timeSeconds*i))
  process_timestamp $timestamp
done

5.1.3、按周打印开始和结束

#!/bin/bash

timeSeconds=$((3600 * 24 * 7))

# 定义函数
process_timestamp() {
  timestamp=$1
  next_hour_timestamp=$((timestamp + $timeSeconds))
  timestampStr=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y-%m-%d'))")
  id=$(python3 -c "from datetime import datetime; print(datetime.fromtimestamp($timestamp).strftime('%Y%m%d'))")
  dateIndex=$(python3 -c "from datetime import datetime, timezone; print(datetime.fromtimestamp($timestamp, timezone.utc).strftime('%Y-%m-%dT%H:%M:%SZ'))")
  current_utc_time=$(date -u +"%Y-%m-%dT%H:%M:%SZ")

  
  echo "id: $id"
  echo "timestampStr: $timestampStr"
  echo "timestamp(s)：$timestamp"
  echo "dateIndex: $dateIndex" 
  echo "next_hour_timestamp(s)：$next_hour_timestamp"
  echo "current_utc_time：$current_utc_time"
}


# 获取当前时间，格式为 yyyy-MM-dd HH:mm:ss
current_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "当前时间：$current_time"

begin_timestamp=$(python3 -c "from datetime import datetime, timedelta, timezone; today = datetime.now(timezone.utc).replace(hour=0, minute=0, second=0, microsecond=0); monday = today - timedelta(days=today.weekday()); begin_time = monday.replace(hour=0, minute=0, second=0); print(int(begin_time.timestamp()))")
