Python 3.6 reads and manipulates file contents

The following is an example of reading and manipulating file contents in Python 3.6. It has a good reference value and I hope it will be helpful to everyone. Let’s take a look together

The python environment used is the latest version 3.6

Several methods of operating files in Python:

Copy file A to file B (keep the original format)

Read the contents of the file and return the List list (load the local dictionary library)

Read the file, Return file content

# 1.将A文件复制到B文件中去(保持原来格式)
def copy_file (inputFile, outputFile, encoding):
 fin = open(inputFile, 'r', encoding=encoding) #以读的方式打开文件
 fout = open(outputFile, 'w', encoding=encoding) #以写得方式打开文件
 for eachLiine in fin.readlines(): #读取文件的每一行
 line = eachLiine.strip() #去除每行的首位空格
 fout.write(line + '\n')
 fin.close()
 fout.close()
# 2. 读取文件中的内容,返回List列表 (加载本地词典库)
def read_file_list(inputFile, encoding):
 results = []
 fin = open(inputFile, 'r', encoding=encoding)
 for eachLiine in fin.readlines():
 line = eachLiine.strip().replace('\ufeff', '')
 results.append(line)
 fin.close()
 return results
# 3.读取文件，返回文件内容
def read_file(path):
 with open(path, 'r+', encoding='UTF-8') as f:
 str = f.read()
 return str.strip().replace('\ufeff', '')
def func():
 pass
if __name__ == '__main__':
 copy_file('../data/test1.txt', '../data/text.txt','UTF-8')
 contents = read_file_list('../dict/time.dict','UTF-8')
 print(contents)
