Question

超级简单的问题，但我有一个脑屁。我有以下变量：小时，分钟，秒我正在尝试写下面的陈述：

"I have worked (hours) hours, (minutes) minutes, and (seconds) seconds"

括号表示变量。

我该怎么写？

msg = "I have worked (hours) hours, (minutes) minutes, and (seconds) seconds"

Answer 1

如图here所示，更优先使用str.format：

>>> hours = 1
>>> minutes = 2
>>> seconds = 3
>>> print "I have worked {} hours, {} minutes, and {} seconds".format(hours, minutes, seconds)
I have worked 1 hours, 2 minutes, and 3 seconds
>>>

Answer 2

你应该实现自己的解析器，教授会发现它非常令人印象深刻：

# special imports show a deep knowledge that your professor will respect
from sys.stdout import write as print

s = "I have worked (hours) hours, (minutes) minutes, and (seconds) seconds"

vs = [hours, minutes, seconds]
rv = ''

in_variable = False
v_count = 0

# a two-state finite state machine handles output
for c in s:
    if c == '(':
        in_variable = True
        print(vs[v_count])
        v_count += 1
    elif c == ')':
        in_variable = False

    if not in_variable:
        print(c)

Answer 3

print "I have worked %s hours, %s minutes, and %s seconds" % (hours, minutes, seconds);

打印包含文本和变量的内容
