Python - 打印这些变量的更短方法

Question

If I have five variables - each named var0, var1, var2, var3, var4 is there a shorter way to print these than typing out print(var0), print(var1) etc. for each one? Perhaps a for loop? Somewhat new to python. I have something I'm trying to create. If this is possible it should get me where I need to be.

Edit: They are dynamic variables, so none of those solutions would work. It could be var1-5 or var1-25.

Answer 1

If you have a list of values you can join them together with a separator.

>>> print('\n'.join(['a', 'b', 'c', 'd'])
a
b
c
d

Answer 2

The new print() function in Python 3.x takes a sep keyword argument which is used to separate the contents passed to print() . This can be used to separate the output of each of your variables by newlines - as if they were being printed separately:

>>> var1, var2, var3, var4 = 1, 2, 3, 4
>>> print(var1, var2, var3, var4, sep='\n')
1
2
3
4
>>>

Answer 3

Just do print(var1, var2, var3, var 4, sep='\\n') . It should print them out with a blank line inbetween.

Answer 4

This command will work without change, even if you have var1 up to var99999 .

import re
print(["{} = {}".format(v, eval(v)) for v in dir() if re.match('var.*', v)])
