1、使用Python的built-in函数readlines() 如果要读取整个文件的数据,可以使用Python的built-in函数readlines()。例如: file =open('myfile.txt','r') all_lines=file.readlines() print(all_lines) 以上代码可以打开文件,读取文件中的所有行,将其存储在all_lines列表中,并打印出来。需要注意的是,该方法不适用于...

content = file.read() line = file.readline() file.close() How to Write to file Thewrite()method is used to write data to a file. It takes a string as an argument and writes it to the file. Alternatively, thewritelines()method allows you to write multiple lines to a file by provi...

for line in open(thefilepath): count += 1 However,xreadlinesdoes not return a sequence, and neither does a loop directly on the file object, so you can’t just uselenin these cases to get the number of lines. Rather, you have to loop and count line by line, as shown in the solu...
