我有一个脚本(除其他外):
所以,由于位置等原因,最简单的方法就是不必拉头发。
或者,我应该以不同的方式组织我的文件吗?

我认为最好的方法是重写第一行,但我可能错了。
我尝试了 fileinput()(使用 inplace = 1 ,你可以打印到你的文件中),我弄得一团糟。
所以,很大程度上受到了@mid的解决方案的启发,这是我的代码: #!/ usr / bin / env Python # - - 编码:utf-8 - -
nom = "chambre"
with open(nom + ".txt", 'r') as file:
data = file.readlines()
remote = int(data[0], 16)
code = int(data[1])
data[1] = str(code + 1)
print hex(remote)
print code
with open(nom + ".txt", 'w') as file:
file.writelines(data)

这解决了您的问题:
with open(SourceFile, 'r') as file:
data = file.readlines()
print "Your data at line 1" + data[0]
data[1] = "New line to insert instead of the 2nd line\n"
with open(SourceFile, 'w') as file:
file.writelines( data )

import io
firstLine = 0x10
secondLine = 0x20
print ("create file")
file = open('test.txt', 'w')
file.write(hex(firstLine) + '\n')
file.write(hex(secondLine) + '\n')
file.flush()
file.close()
file2 = open('test.txt', 'r')
print ("create file done")
print ("read file")
first = file2.readline()
second = file2.readline()
firstLineOut = int(first,16)
print ('First: ', hex(firstLineOut))
secondLineOut = int(second,16)
print ('Second: ', hex(secondLineOut))
file2.close()
print ("update file")
secondLineOut += 1
print ('Second New: ', hex(secondLineOut))
file2 = open('test.txt', 'w')
file2.write(hex(firstLineOut) + '\n')
file2.write(hex(secondLineOut) + '\n')
file2.flush()
file2.close()
print ('done')
