问题：如何在Python的同一行上打印变量和字符串？
我正在使用python算出如果一个孩子每7秒出生一次，那么5年内将有多少个孩子出生。问题出在我的最后一行。当我在文本的任何一侧打印文本时，如何使它工作？
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"

使用,分隔字符串和变量，同时打印：
print "If there was a birth every 7 seconds, there would be: ",births,"births", 在print语句中将项目分隔一个空格：
>>> print "foo","bar","spam"
foo bar spam或更好地使用字符串格式：
print "If there was a birth every 7 seconds, there would be: {} births".format(births)字符串格式化功能强大得多，它还允许您执行其他一些操作，例如：填充，填充，对齐，宽度，设置精度等
>>> print "{:d} {:03d} {:>20f}".format(1,2,1.1)
1 002 1.100000
^^^
0's padded to 2演示：
>>> births = 4
>>> print "If there was a birth every 7 seconds, there would be: ",births,"births"
If there was a birth every 7 seconds, there would be: 4 births
#formatting
>>> print "If there was a birth every 7 seconds, there would be: {} births".format(births)
If there was a birth every 7 seconds, there would be: 4 births回答 1
还有两个
第一个
>>>births = str(5)
>>>print "there are " + births + " births."
there are 5 births.添加字符串时，它们会串联在一起。
第二个
同样format，字符串的（Python 2.6和更高版本）方法可能是标准方法：
>>> births = str(5)
>>>
>>> print "there are {} births.".format(births)
there are 5 births.此format方法也可以与列表一起使用
>>> format_list = ['five','three']
>>> print "there are {} births and {} deaths".format(*format_list) #unpack the list
there are five births and three deaths或字典
>>> format_dictionary = {'births': 'five', 'deaths': 'three'}
>>> print "there are {births} births, and {deaths} deaths".format(**format_dictionary) #yup, unpack the dictionary
there are five births, and three deaths回答 2
Python是一种非常通用的语言。您可以通过不同的方法打印变量。我列出了以下4种方法。您可以根据需要使用它们。
例：
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}')输出为：
I have 1 ball回答 3
如果要使用python 3，它非常简单：
print("If there was a birth every 7 second, there would be %d births." % (births))回答 4
从python 3.6开始，您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回答 5
您可以使用f-string或.format（）方法
使用f弦
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))回答 6
您可以使用格式字符串：
print "There are %d births" % (births,)或在这种简单情况下：
print "There are ", births, "births"回答 7
如果您使用的是python 3.6或最新版本，则f-string是最佳和简便的选择
print(f"{your_varaible_name}")回答 8
您将首先创建一个变量：例如：D =1。然后执行此操作，但是将字符串替换为所需的任何内容：
D = 1
print("Here is a number!:",D)回答 9
在当前的python版本上，您必须使用括号，如下所示：
print ("If there was a birth every 7 seconds", X)回答 10
使用字符串格式
print("If there was a birth every 7 seconds, there would be: {} births".format(births))
# Will replace "{}" with births如果您在进行玩具项目，请使用：
print('If there was a birth every 7 seconds, there would be:' births'births) 要么
print('If there was a birth every 7 seconds, there would be: %d births' %(births))
# Will replace %d with births回答 11
您可以使用字符串格式来执行此操作：
print "If there was a birth every 7 seconds, there would be: %d births" % births或者您可以提供print多个参数，它将自动用空格分隔它们：
print "If there was a birth every 7 seconds, there would be:", births, "births"回答 12
我将您的脚本复制并粘贴到.py文件中。我使用Python 2.7.10原样运行它，并收到了相同的语法错误。我还在Python 3.5中尝试了该脚本，并收到以下输出：
File "print_strings_on_same_line.py", line 16
print fiveYears
^
SyntaxError: Missing parentheses in call to 'print'然后，我修改了最后一行，其中打印了出生人数，如下所示：
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: " + str(births) + " births"输出为（Python 2.7.10）：
157680000
If there was a birth every 7 seconds, there would be: 22525714 births我希望这有帮助。

只需在之间使用，（逗号）。
请参阅以下代码以获得更好的理解：
# 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")回答 14
稍有不同：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]," ~~")回答 15
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))回答 16
如果在字符串和变量之间使用逗号，如下所示：
print "If there was a birth every 7 seconds, there would be: ", births, "births"
