# 打开文件file_path = "data.txt"file = open(file_path, "r")# 使用read()函数读取整个文件内容content = file.read()# 关闭文件file.close()# 打印文件内容print(content)在上述代码中，我们首先使用open()函数打开一个文件，并指定模式为"r"，表示读取文件内容。然后使用read()函数读取整个文件内容，并...
file.writelines(lines) 1. 2. 4. 关闭文件 在文件操作完成后,我们需要使用 close() 函数关闭文件。 file.close() 1. 在Python 中,打开的文件对象必须显式地关闭,否则可能会导致内存泄漏等问题。 5. 使用 with 语句 在Python 中,我们可以使用 with 语句来自动管理文件对象的生命周期。使用 with 语句可以避免...
data = f.read() print(type(data)) #<class 'str'> print(data) f.close() ##readline的使用 f = open(r"C:\Users\Wings\.spyder-py3\故意杀人.txt", "r", encoding="utf-8") for i in range(3): data = f.readline() print(data) f.close() f = open(r"C:\Users\Wings\.spyder-...
data=open("demo.txt","r").read(-1) print(data) 执行结果: A threadisa basic unitofCPU execution. It must dependonthe process surviving. A threadisan execution context, whichiswhat a CPU needs to execute A listofinstructions. In Python, multithreading takes longer. 2. size为0时 当size...
Python read binary file In the following example, we read a binary file. read_binary.py #!/usr/bin/python with open('web.png', 'rb') as f: hexdata = f.read().hex() n = 2 data = [hexdata[i:i+n] for i in range(0, len(hexdata), n)] i = 0 for e in data: print(...
We can read text data in Python with the built-inopenfunction or thepathlibmodule. ThePath.read_textreads the contents of the file as a string. Theopenfunction is used to open files in Python. open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None) ...

try: f = open('/path/to/file', 'r') print(f.read()) finally: if f: f.close() 但是每次都这么写实在太繁琐,所以,Python引入了with语句来自动帮我们调用close()方法: with open('/path/to/file', 'r') as f: print(f.read()) 2. python文件对象提供了三个“读”方法: read()、readline...
