Python 如何右对齐名称列表
我一直在开发一个程序,要求用户输入一个姓名列表。在他们输入这些名称后,我的程序必须右对齐所有这些名称。这就是我到目前为止所做的:Python 如何右对齐名称列表,python,python-3.x,Python,Python 3.x,我一直在开发一个程序,要求用户输入一个姓名列表。在他们输入这些名称后,我的程序必须右对齐所有这些名称。这就是我到目前为止所做的: names =[] # User is prompted to enter a list of names name = input ("Enter strings (end with DONE):\n") while name != 'DONE': names.append(name) # This appends/adds the name(s) the
names =[]
# User is prompted to enter a list of names
name = input ("Enter strings (end with DONE):\n")
while name != 'DONE':
names.append(name) # This appends/adds the name(s) the user types in, to names
name = input("")
print("\n""Right-aligned list:")
for name in names:
maximum = max(names, key=len) #This line of code searches for the name which is the longest
new_maximum = len(maximum) #Here it determines the length of the longest name
diff = new_maximum - len(name) #This line of code is used to subtract the length of the longest name from the length of another different name
title = diff*' ' #This code determines the open space (as the title) that has to be placed in front of the specific name
print(title,name)
以下是没有所有注释的程序:
names =[]
name = input ("Enter strings (end with DONE):\n")
while name != 'DONE':
names.append(name)
name = input("")
print("\n""Right-aligned list:")
for name in names:
maximum = max(names, key=len)
new_maximum = len(maximum)
diff = new_maximum - len(name)
title = diff*' '
print(title,name)
我希望此程序的输出为:
Enter strings (end with DONE):
Michael
James
Thabang
Kelly
Sam
Christopher
DONE
Right-aligned list:
Michael
James
Thabang
Kelly
Sam
Christopher
相反,我得到的是:
Enter strings (end with DONE):
Michael
James
Thabang
Kelly
Sam
Christopher
DONE
Right-aligned list:
Michael
James
Thabang
Kelly
Sam
Christopher
注意:当用户输入DONE时,提示结束
问题是列表中的每个名字都有一个额外的空格。如何在没有额外空格的情况下将其右对齐打印?您可以按如下方式使用字符串格式:
a = ['a', 'b', 'cd', 'efg']
max_length = max(len(i) for i in a)
for item in a:
print '{0:>{1}}'.format(item, max_length)
[OUTPUT]
a
b
cd
efg
我知道这是一个老生常谈的问题,但这只需要一句话:
print('\n'.join( [ name.rjust(len(max(names, key=len))) for name in names ] ))
这个列表理解的答案帮助了我:有什么问题吗?你几乎有相同的输出…每个单词的左边多了一个空格,但我现在有了正确的答案。无论如何,谢谢你。你对这个问题有一个很好的答案。然而,为了简单地纠正您的版本中的问题,只需要有额外的空间就成了问题。额外的空间来自对
print()
函数使用多个参数。所有参数将用空格分隔。您想要做的是将title
和name
变量连接起来并打印出来。
