有没有办法在Python的高级字符串格式"foo {}".格式(bar)中添加条件字符串？

Question

例如,我有一行这样的代码

if checked:
    checked_string = "check"
else:
    checked_string = "uncheck"

print "You can {} that step!".format(checked_string)

这有什么捷径吗？我只是好奇而已.

Answer 1

print "You can {} that step!".format('check' if checked else 'uncheck')

Answer 2

这可以通过 python 3.6+ 使用 f 字符串来处理

print(f"You can {'check' if checked else 'uncheck'} that step!")

Answer 3

checkmap = {True: 'check', False: 'uncheck'}
print "You can {} that step!".format(checkmap[bool(checked)]))
