我用python计算出如果每7秒出生一个孩子5年内会有多少个孩子出生。问题在我的最后一行。我如何得到一个变量的工作时，我打印文本的任何一方?
这是我的代码:
currentPop = 312032486
oneYear = 365
hours = 24
minutes = 60
seconds = 60
# seconds in a single day
secondsInDay = hours * minutes * seconds
# seconds in a year
secondsInYear = secondsInDay * oneYear
fiveYears = secondsInYear * 5
#Seconds in 5 years
print fiveYears
# fiveYears in seconds, divided by 7 seconds
births = fiveYears // 7
print "If there was a birth every 7 seconds, there would be: " births "births"
当前回答
如果你在字符串和变量之间使用逗号，就像这样:
print "If there was a birth every 7 seconds, there would be: ", births, "births"
其他回答
你可以使用字符串格式化来做到这一点:
print "If there was a birth every 7 seconds, there would be: %d births" % births
或者你可以给print多个参数，它会自动用一个空格分隔它们:
print "If there was a birth every 7 seconds, there would be:", births, "births"
你可以使用格式化字符串:
print "There are %d births" % (births,)
或者在这个简单的例子中:
print "There are ", births, "births"
略有不同:使用Python 3并在同一行中打印几个变量:
print("~~Create new DB:",argv[5],"; with user:",argv[3],"; and Password:",argv[4]," ~~")
如果你使用的是python 3.6或最新版本， f弦是最好的，也是最简单的
print(f"{your_varaible_name}")
在当前的python版本中，您必须使用括号，如下所示:
print ("If there was a birth every 7 seconds", X)
