我无法将文本文件中的数字添加到我的列表中，也不知道如何添加。
到目前为止的代码:
def add_player_points():
# Allows the user to add a points onto the players information.
L = open("players.txt","r+")
name = raw_input("\n\tPlease enter the name of the player whose points you wish to add: ")
for line in L:
s = line.strip()
string = s.split(",")
if name == string[0]:
opponent = raw_input("\n\t Enter the name of the opponent: ")
points = raw_input("\n\t Enter how many points you would like to add?: ")
new_points = string[7] + points
L.close()
这是文本文件中的 key 示例。文件中大约有100个:
Joe,Bloggs,J.bloggs@anemailaddress.com,01269 512355, 1, 0, 0, 0,
^
我希望将此数字添加到的值是 0 以及已经存在的数字，由其下方的箭头指示。如图所示，文本文件名为 players.txt。
完整的代码答案会很有帮助。
请您参考如下方法:
我不喜欢我之前写的东西，而且这个用例对于 fileinput 来说不是最佳的。我从源代码中获取了一段类似的代码，并根据您的需要进行了调整。
请注意，对于您修改的每一行，您都在重新编写整个文件。如果性能是一个问题，我强烈建议改变你处理数据的方式。
这段代码仍然有效。
from tempfile import mkstemp
from shutil import move
from os import remove, close
def add_player_points():
file_path = "test.txt"
name = raw_input("\n\tPlease enter the name of the player whose points you wish to add: ")
#Create temp file
fh, abs_path = mkstemp()
with open(abs_path,'w') as new_file:
with open(file_path) as old_file:
for line in old_file:
stripped_line = line.strip()
split_string = stripped_line.split(",")
print name == split_string[0]
if name == split_string[0]:
opponent = raw_input("\n\t Enter the name of the opponent: ")
points = raw_input("\n\t Enter how many points you would like to add?: ")
temp = int(split_string[5]) + int(points) # fool proofing the code
split_string[5] = str(temp)
stripped_line = ','.join(split_string)# line you shove back into the file.
print stripped_line
new_file.write(stripped_line +'\n')
else:
new_file.write(line)
close(fh)
#Remove original file
remove(file_path)
#Move new file
move(abs_path, file_path)
您不会认为这是一个大问题，但事实确实如此。
另一个提示:可能需要检查模块 csv - 文件编辑可能比我在这里展示的更智能。
