为了支持多种操作系统的使用: 文件。写(f'some字符串和/或{variable}。{os.linesep}”)

我真的不想每次都输入\n， @matthause的答案似乎不适合我，所以我创建了自己的类

class File():

    def __init__(self, name, mode='w'):
        self.f = open(name, mode, buffering=1)
        
    def write(self, string, newline=True):
        if newline:
            self.f.write(string + '\n')
        else:
            self.f.write(string)

这就是它的实现

f = File('console.log')

f.write('This is on the first line')
f.write('This is on the second line', newline=False)
f.write('This is still on the second line')
f.write('This is on the third line')

这应该在日志文件中显示为

This is on the first line
This is on the second lineThis is still on the second line
This is on the third line

file_path = "/path/to/yourfile.txt"
with open(file_path, 'a') as file:
    file.write("This will be added to the next line\n")

or

log_file = open('log.txt', 'a')
log_file.write("This will be added to the next line\n")

对我来说，在print()语句上使用append (a)和open()看起来更容易:

save_url  = ".\test.txt"

your_text = "This will be on line 1"
print(your_text, file=open(save_url, "a+"))

another_text = "This will be on line 2"
print(another_text, file=open(save_url, "a+"))

another_text = "This will be on line 3"
print(another_text, file=open(save_url, "a+"))

请注意，该文件在Python 3中不支持，已被删除。你可以用open内置函数做同样的事情。

f = open('test.txt', 'w')
f.write('test\n')

通常你会使用\n，但无论出于什么原因，在Visual Studio Code 2019 Individual中它将无法工作。但是你可以用这个:

# Workaround to \n not working
print("lorem ipsum", file=f)  # Python 3.0 onwards only
print >>f, "Text"             # Python 2.0 and under
