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))

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))
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是一种非常通用的语言。你可以用不同的方法打印变量。我列出了以下五种方法。您可以根据自己的方便使用它们。
例子:
a = 1
b = 'ball'
方法1:
print('I have %d %s' % (a, b))
方法2:
print('I have', a, b)
方法3:
print('I have {} {}'.format(a, b))
方法4:
print('I have ' + str(a) + ' ' + b)
方法5:
print(f'I have {a} {b}')
输出将是:
I have 1 ball
从python 3.6开始，你可以使用文字字符串插值。
births = 5.25487
>>> print(f'If there was a birth every 7 seconds, there would be: {births:.2f} births')
If there was a birth every 7 seconds, there would be: 5.25 births
