我正在使用python算出如果一個(gè)孩子每7秒出生一次，那么5年內(nèi)將有多少個(gè)孩子出生。問題出在我的最后一行。當(dāng)我在文本的任何一側(cè)打印文本時(shí)，如何使它工作？這是我的代碼：currentPop = 312032486oneYear = 365hours = 24minutes = 60seconds = 60# seconds in a single daysecondsInDay = hours * minutes * seconds# seconds in a yearsecondsInYear = secondsInDay * oneYearfiveYears = secondsInYear * 5#Seconds in 5 yearsprint fiveYears# fiveYears in seconds, divided by 7 secondsbirths = fiveYears // 7print "If there was a birth every 7 seconds, there would be: " births "births"

使用,分隔字符串和變量，同時(shí)打?。?/p>
print("If there was a birth every 7 seconds, there would be: ", births, "births")
, in print功能將項(xiàng)目分隔為一個(gè)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))
字符串格式化功能更強(qiáng)大，它還允許您執(zhí)行其他操作，例如填充，填充，對(duì)齊，寬度，設(shè)置精度等。
>>> print("{:d} {:03d} {:>20f}".format(1, 2, 1.1))
1 002 1.100000

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

Python是一種非常通用的語(yǔ)言。您可以通過不同的方法打印變量。我列出了以下五種方法。您可以根據(jù)需要使用它們。
例子：
a = 1b = '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} ')輸出為：
I have 1 ball

還有兩個(gè)
第一個(gè)
>>> births = str(5)
>>> print("there are " + births + " births.")
there are 5 births.
添加字符串時(shí)，它們會(huì)串聯(lián)在一起。
第二個(gè)
同樣format，字符串的（Python 2.6和更高版本）方法可能是標(biāo)準(zhǔn)方法：
>>> births = str(5)
>>>
>>> print("there are {} births.".format(births))
there are 5 births.
此format方法也可以與列表一起使用
>>> format_list = ['five', 'three']
>>> # * unpacks the list:
>>> print("there are {} births and {} deaths".format(*format_list))
there are five births and three deaths
或字典
>>> format_dictionary = {'births': 'five', 'deaths': 'three'}
>>> # ** unpacks the dictionary
>>> print("there are {births} births, and {deaths} deaths".format(**format_dictionary))
there are five births, and three deaths
