Python 如何让打印声明告诉我作者的日期'；死亡？

我试图让它说“作者”死于“日期”，但它不起作用

authors = {
   "Charles Dickens": "1870",
   "William Thackeray": "1863",
   "Anthony Trollope": "1882",
   "Gerard Manley Hopkins": "1889"
   }
for author, date in authors.items():
   print( "%s" % authors + " died in "  + date)

---

您只需将打印中变量的名称从authors（您的完整dict）更改为author，表示集合的每个实例：

authors = {
   "Charles Dickens": "1870",
   "William Thackeray": "1863",
   "Anthony Trollope": "1882",
   "Gerard Manley Hopkins": "1889"
   }
for author, date in authors.items():
    print( "%s" % author + " died in "  + date)

这将产生以下输出：

Charles Dickens died in 1870
William Thackeray died in 1863
Anthony Trollope died in 1882
Gerard Manley Hopkins died in 1889

---

您可以使用该格式

authors = {
   "Charles Dickens": "1870",
   "William Thackeray": "1863",
   "Anthony Trollope": "1882",
   "Gerard Manley Hopkins": "1889"
   }
for author, date in authors.items():
     print('{}, in {}'.format(author, date)))

或f-string Python 3.6及以上版本

for author, date in authors.items():
   print('{author}, in {date}'))

输出

Charles Dickens, in 1870
William Thackeray, in 1863
Anthony Trollope, in 1882
Gerard Manley Hopkins, in 1889

---

以下是简单易懂的解决方案

for author, date in authors.items():
   print( author + " died in "  + date)

输出

Charles Dickens died in 1870
William Thackeray died in 1863
Anthony Trollope died in 1882
Gerard Manley Hopkins died in 1889

---

您需要将

print

语句中的

authors

更改为

author

， 您可以使用多种打印样式，明智地选择其中一种

authors = {
   "Charles Dickens": "1870",
   "William Thackeray": "1863",
   "Anthony Trollope": "1882",
   "Gerard Manley Hopkins": "1889"
   }
for author, date in authors.items():
   #your statement
   print( "%s" % author + " died in "  + date)

   #using f before the string for python 3.6 and above
   print(f"{author} died in {date}")


   #using format() method of string
   print("{0} died in {1}".format(author,date))

   #using string concatenation
   print(author + " died in "+date)

每个语句都打印相同的输出，但有些技术比其他技术更有用，例如使用

f

或

format（）

可以为您提供更大的灵活性

查尔斯·狄更斯，1870年威廉·萨克雷，1863年安东尼·特罗洛普，1882年杰拉德·曼利·霍普金斯，1889年这就是不断出现的{“查尔斯·狄更斯：'1870”，“威廉·萨克雷：'1863”，“安东尼·特罗洛普：'1882”，“杰拉德·曼利·霍普金斯：'1889}死于1870年{'Charles Dickens'：'1870'，'William Thackray'：'1863'，'Anthony Trollope'：'1882'，'Gerard Manley Hopkins'：'1889'}死于1863{'Charles Dickens'：'1870'，'William Thackray'：'1863'，'Anthony Trollope'：'1882'，'Gerard Manley Hopkins'：'1889'}死于1882年{'Charles Dickens'：'1870'，'William Thackray'：'1863'，'Anthony Trollope'：'1882'，'Gerard Manley Hopkins'：'1889'}死亡于1889年虽然这可能回答了这个问题，但添加一些额外的信息，解释代码的作用是很有用的。请注意，f-strings仅为python 3.6及以上版本。对于该注释，Tnx的答案与上面的答案相同。有什么不同？我使用了字符串串联

authors = {
   "Charles Dickens": "1870",
   "William Thackeray": "1863",
   "Anthony Trollope": "1882",
   "Gerard Manley Hopkins": "1889"

   #your statement
   print( "%s" % author + " died in "  + date)

   #using f before the string for python 3.6 and above
   print(f"{author} died in {date}")


   #using format() method of string
   print("{0} died in {1}".format(author,date))

   #using string concatenation
   print(author + " died in "+date)
