Sorting a text file alphabetically (Python)
提问by Bocui
I would like to sort the file 'shopping.txt' in alphabetical order
我想按字母顺序对文件“shopping.txt”进行排序
shopping = open('shopping.txt')
line=shopping.readline()
while len(line)!=0:
print(line, end ='')
line=shopping.readline()
#for eachline in myFile:
# print(eachline)
shopping.close()

Use sortedfunction.
使用sorted功能。
with open('shopping.txt', 'r') as r:
for line in sorted(r):
print(line, end='')
回答by Mezgrman
An easy way to do this is using the sort()or sorted()functions.
一个简单的方法是使用sort()orsorted()函数。
lines = shopping.readlines()
lines.sort()
Alternatively:
或者：
lines = sorted(shopping.readlines())
The disadvantage is that you have to read the whole file into memory, though. If that's not a problem, you can use this simple code.
但是，缺点是您必须将整个文件读入内存。如果这不是问题，您可以使用这个简单的代码。

Just to show something different instead of doing this in python, you can do this from a command line in Unix systems:
只是为了显示一些不同的东西而不是在 python 中执行此操作，您可以从 Unix 系统中的命令行执行此操作：
sort shopping.txt -o shopping.txt
and your file is sorted. Of course if you really want python for this: solution proposed by a lot of other people with reading file and sorting works fine
并且您的文件已排序。当然，如果你真的想要 python：很多其他人提出的解决方案阅读文件和排序工作正常
