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+"))

你可以使用:

file.write(your_string + '\n')

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")

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

你可以这样做:

file.write(your_string + '\n')

正如另一个答案所建议的，但为什么在可以调用文件时使用字符串连接(缓慢，容易出错)。写两次:

file.write(your_string)
file.write("\n")

注意，写操作是被缓冲的，所以两者是一样的。

另一个解决方案是使用fstring从列表中写入

lines = ['hello','world']
with open('filename.txt', "w") as fhandle:
  for line in lines:
    fhandle.write(f'{line}\n')

作为一个函数

def write_list(fname, lines):
    with open(fname, "w") as fhandle:
      for line in lines:
        fhandle.write(f'{line}\n')

write_list('filename.txt', ['hello','world'])
