Python 如何将带有字符串和整数的列表打印到文本文件中

Question

这是我的清单

[('Doctor', 1), ('Paramedic', 2), ('Janitor', 3)]

我想将列表打印到文本文件中，看起来像这样，

('Doctor', 1), ('Paramedic', 2), ('Janitor', 3)

或类似的东西。

谢谢。

Answer 1

最简单的方法是convert list to string并使用slicing remove parenthesis并将write it to file

不需要任何loop

a = [('Doctor', 1), ('Paramedic', 2), ('Janitor', 3)]
a = str(a)[1:-1]
f = open("demofile2.txt", "a")
f.write(str(a))
f.close()

Answer 2

这是一个可能的解决方案：

LST = [('Doctor', 1), ('Paramedic', 2), ('Janitor', 3)]
OUTPUTFILE = "out.txt" # text file path

with open(OUTPUTFILE, "w") as f:
    for name, count in LST:
        f.write(f"{name}: {count}\n")            

Answer 3

some_list = [('Doctor', 1), ('Paramedic', 2), ('Janitor', 3)] with open('file.txt', 'w') as file: for item in some_list: file.write(f'{item}, ')
