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"

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))

其他回答

你可以使用f-string或.format()方法

使用f-string

print(f'If there was a birth every 7 seconds, there would be: {births} births')

使用.format ()

print("If there was a birth every 7 seconds, there would be: {births} births".format(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")

如果你想使用python 3,这很简单:

print("If there was a birth every 7 second, there would be %d 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"
