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
你首先要创建一个变量:例如:D = 1。然后这样做，但替换字符串与任何你想要:
D = 1
print("Here is a number!:",D)
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"
在中间用，(逗号)就可以了。
为了更好地理解，请参阅下面的代码:
# Weight converter pounds to kg
weight_lbs = input("Enter your weight in pounds: ")
weight_kg = 0.45 * int(weight_lbs)
print("You are ", weight_kg, " kg")
PYTHON 3
最好使用格式选项
user_name=input("Enter your name : )
points = 10
print ("Hello, {} your point is {} : ".format(user_name,points)
或将输入声明为字符串并使用
user_name=str(input("Enter your name : ))
points = 10
print("Hello, "+user_name+" your point is " +str(points))
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}")
