這篇文章主要為大家詳細(xì)介紹了如何編寫一個py腳本,可以實現(xiàn)自定義替換py文件里面指定內(nèi)容,感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

環(huán)境

python3.10

問題描述

如何寫個py腳本，自定義替換py文件里面指定內(nèi)容：1.py里面的192.168.1.7:11434替換為192.168.1.7:11435

解決方案

1.單個內(nèi)容替換，1.py文件里面的192.168.1.7:11434替換為192.168.1.7:11435

import os

def replace_content_in_file(file_path, old_string, new_string):
    """Replace all occurrences of old_string with new_string in the file."""
    # Check if the file exists
    if not os.path.exists(file_path):
        print(f"文件 {file_path} 不存在")
        return
    
    # Read the content of the file
    with open(file_path, 'r', encoding='utf-8') as file:
        content = file.read()
    
    # Replace the old string with the new string
    updated_content = content.replace(old_string, new_string)
```bash
    
    # Write the updated content back to the file
    with open(file_path, 'w', encoding='utf-8') as file:
        file.write(updated_content)
    
    print(f"成功替換 {old_string} 為 {new_string} 在文件 {file_path}")

# Specify the file path and strings to replace
file_path = '1.py'
old_string = '192.168.1.7:11434'
new_string = '192.168.1.7:11435'

# Call the function to replace content
replace_content_in_file(file_path, old_string, new_string)

2.填寫具體文件夾路徑folder_path = '/home/user/scripts/'下面的1.py文件里面的192.168.1.7:11434替換為192.168.1.7:11435

import os

def replace_content_in_file(file_path, old_string, new_string):
    """Replace all occurrences of old_string with new_string in the file."""
    # Check if the file exists
    if not os.path.exists(file_path):
        print(f"文件 {file_path} 不存在")
        return
    
    # Read the content of the file
    with open(file_path, 'r', encoding='utf-8') as file:
        content = file.read()
    
    # Replace the old string with the new string
    updated_content = content.replace(old_string, new_string)
    
    # Write the updated content back to the file
    with open(file_path, 'w', encoding='utf-8') as file:
        file.write(updated_content)
    
    print(f"成功替換 {old_string} 為 {new_string} 在文件 {file_path}")

# Specify the folder path and file name
folder_path = '/home/user/scripts/'
file_name = '1.py'
file_path = os.path.join(folder_path, file_name)

# Strings to replace
old_string = '192.168.18.7:11434'
new_string = '192.168.18.7:11435'

# Call the function to replace content
replace_content_in_file(file_path, old_string, new_string)

3.不同文件夾多文件替換

import os

def replace_content_in_file(file_path, old_string, new_string):
    """Replace all occurrences of old_string with new_string in the file."""
    # Check if the file exists
    if not os.path.exists(file_path):
        print(f"文件 {file_path} 不存在")
        return
    
    # Read the content of the file
    try:
        with open(file_path, 'r', encoding='utf-8') as file:
            content = file.read()
    except Exception as e:
        print(f"讀取文件 {file_path} 時出錯: {e}")
        return
    
    # Replace the old string with the new string
    updated_content = content.replace(old_string, new_string)
    
    # Write the updated content back to the file
    try:
        with open(file_path, 'w', encoding='utf-8') as file:
            file.write(updated_content)
        print(f"成功替換 {old_string} 為 {new_string} 在文件 {file_path}")
    except Exception as e:
        print(f"寫入文件 {file_path} 時出錯: {e}")

# Specify the files and their respective folder paths
files_to_replace = [
    {'folder': '/path/to/w', 'file': '1.py'},
    {'folder': '/path/to/x', 'file': '2.py'}
]

# Strings to replace
old_string = '192.168.16.7:11434'
new_string = '192.168.16.7:11435'

# Iterate over each file and its folder path
for entry in files_to_replace:
    folder_path = entry['folder']
    file_name = entry['file']
    file_path = os.path.join(folder_path, file_name)
    replace_content_in_file(file_path, old_string, new_string)

4.最后腳本

python th.py

import os
import chardet
def detect_file_encoding(file_path):
    """檢測文件的實際編碼"""
    with open(file_path, 'rb') as file:
        raw_data = file.read()
        result = chardet.detect(raw_data)
        return result['encoding']
def replace_content_in_file(file_path, old_string, new_string):
    """替換文件中的所有old_string為new_string"""
    # 檢查文件是否存在
    if not os.path.exists(file_path):
        print(f"文件 {file_path} 不存在")
        return
    
    try:
        # 檢測文件編碼
        encoding = detect_file_encoding(file_path)
        print(f"檢測到文件編碼: {encoding}")
        
        # 讀取文件內(nèi)容
        with open(file_path, 'r', encoding=encoding) as file:
            content = file.read()
            print(f"替換前內(nèi)容:\n{content}")
        
        # 替換內(nèi)容
        updated_content = content.replace(old_string, new_string)
        if updated_content == content:
            print(f"未找到 {old_string}，無需替換")
            return
        
        # 寫入更新后的內(nèi)容
        with open(file_path, 'w', encoding=encoding) as file:
            file.write(updated_content)
        
        print(f"成功替換 {old_string} 為 {new_string} 在文件 {file_path}")
        print(f"替換后內(nèi)容:\n{updated_content}")
    
    except PermissionError:
        print(f"權(quán)限不足，無法訪問文件 {file_path}")
    except Exception as e:
        print(f"處理文件 {file_path} 時出錯: {e}")
def main():
    # 指定文件和文件夾路徑
    files_to_replace = [
        {'folder': '/mnt/e/work/metahuman-stream/web/realtalk/examples', 'file': 'index.html'},
        {'folder': '/mnt/e/work/metahuman-stream/web/realtalk/examples', 'file': 'index_noauto.js'}
    ]
    # 要替換的字符串
    old_string = '192.168.18.7:11434'
	  new_string = '192.168.18.7:11435'
    # 遍歷每個文件并進(jìn)行替換
    for entry in files_to_replace:
        folder_path = entry['folder']
        file_name = entry['file']
        file_path = os.path.join(folder_path, file_name)
        
        print(f"\n正在處理文件: {file_path}")
        replace_content_in_file(file_path, old_string, new_string)
if __name__ == "__main__":
    print("腳本開始執(zhí)行...")
    main()
    print("腳本執(zhí)行完成。")
