Question

我正在制作一个与Xbee和python有关的应用程序，在这里我需要从文本文件读取数据，然后从文本文件中找出最大路由器值。我的文本文件包含以下数据：

0013A20040C8316D - 0  0013A20040C8315B - 3  0013A20040C8316D - 1  0013A20041C8315B - 5 0013A20040C8316D - 4  0013A20045C8315B - 7

我尝试了以下代码：

 file= open("myFile.txt","r")
 dataRead= file.read()
 dataReadInString= str(dataRead)
 dataReadAfterRemovingString= dataReadInString.replace(" ","")
 #print(dataReadInString)
 print(dataReadAfterRemovingString)


Is there some way to get the value of 7(i.e, the highest number) from the textfile by reading the textfile. I am new to python . Please help.

我会尽可能回答清楚。我们将假定您的文件为常规方案：id1 - name1 id2 - name2 ...

下面是代码的详细信息：

file= open("myFile.txt","r")

# read file
dataReadInString = file.read()
# Remove line return
dataReadInString = dataReadInString.replace("\n", "")
print(dataReadInString)

# Create list for each element (id + name)
dataReadAfterRemovingString = dataReadInString.split("  ")
print(dataReadAfterRemovingString)

# New list that will have the ids
list_number = []

# Iterate for each element
for mot in dataReadAfterRemovingString:
    # Create list with [id, name]
    list_elt = mot.split(" - ")

    # Append to the list of id the current id
    list_number.append(list_elt[0])

# Display list of ID
print(list_number)
# ['0013A20040C8316D', '0013A20040C8315B', '0013A20040C8316D', '0013A20041C8315B', '0013A20045C8315B']

希望这个答案，任何问题，提出评论。
