Try using join:
尝试使用join：
print "\n"+'|'.join([id,var1,var2,var3,var4])
or if the variables aren't already strings:
或者如果变量不是字符串：
print "\n"+'|'.join(map(str,[id,var1,var2,var3,var4]))
The benefit of this approach is that you don't have to build a long format string and it basically works unchanged for an arbitrary number of variables.
这种方法的好处是你不必构建一个长格式字符串，它基本上对任意数量的变量都没有改变。

For a variable number of values:
对于可变数量的值：
print '|%s|' % '|'.join(str(x) for x in [id, var1, var2, var3, var4])
#3

print "\n|%s|%s|%s|%s" % (id,var1,var2,var3,var4)

Edit: The other answers with join are better. Join expects strings.

If you are using Python 2.6 or newer, use the new standard for formating string, the str.format method:
如果您使用的是Python 2.6或更高版本，请使用新标准格式化字符串str.format方法：
print "\n{0}|{1}|{2}|".format(id,var1,var2)
