[英]How would I make Python read a file line and use it as a variable?
Tried looking it up elsewhere, to no avail. 试图在其他地方查找它,无济于事。 How would I do something like, having Python read a file line, then use what's in that line as a variable for a different file?
我该怎么做,让Python读取文件行,然后将该行中的内容用作另一个文件的变量?
Essentially, I want a different file that acts as a verification key, and when the content of the file (the passkey) is entered, my code recognizes that and passes it, then opening said file. 本质上,我想要一个不同的文件作为验证密钥,并且当输入文件的内容(密码)时,我的代码会识别出该文件并将其传递,然后打开该文件。 I also want to be able to read a lockout file to check and see whether the user should be "locked out", and need to enter the passkey.
我还希望能够读取锁定文件,以检查并查看用户是否应该“锁定”,并且需要输入密码。 Any possible way of doing this?
有任何可行的方法吗?
Update: I edited the code a little by my self, just so everyone is aware. 更新:我亲自编辑了一下代码,以便每个人都知道。
filename = ".UbuntuAlt/.Info.txt"
#I'm aware that the use of many of the "quit()" functions is ambiguous but idc
verify = ".UbuntuAlt/.Verify.txt"
locktxt = ".UbuntuAlt/.Lockout.txt"
#this is where I want to make ".Lockout.txt" verify whether the passkey needs to be used, and set variable "lockout" accordingly
infotxt = open(filename, "r")
verifyread = open(verify, "r")
locktestw = open(locktxt, "w")
locktestr = open(locktxt, "r")
if lockout == True:
verify1 = raw_input("Please enter verification key: ")
#this is where I want the code to read ".Verify.txt" and use its content as the passkey
if verify1 == "look above":
for line in infotxt:
print line,
infotxt.close()
verifyread.close()
lockout = False
#this is where I want ".Lockout.txt" edited to be false-- I can do that myself though
lockoutq = raw_input("Lockout is disabled. Reenable? [Y/n]: ")
if lockoutq == "y" or "Y" or " ":
#also where I plan on editing it
quit()
if lockoutq == "n" or "N":
quit()
else:
lockdownerr = raw_input("Invalid input. [2] attempts remaining. Reenable? [Y/n]: ")
if lockdownerr == "y" or "Y" or " ":
#aaa
quit()
if lockdownerr == "n" or "N":
quit()
else:
lockdownfinal = raw_input("Invalid input. [1] attempt remaining. Reenable? [Y/n]: ")
if lockdownerr == "y" or "Y" or " ":
#aaa
quit()
if lockdownerr == "n" or "N":
quit()
else:
print "Invalid input. Enabling anyway."
#you get the point
quit()
else:
verifyread.close()
print "You've inputted an invalid key. Aborting."
quit()
else:
for line in infotxt:
print line,
infotxt.close()
verifyread.close()
lockoutq2 = raw_input("Lockout is disabled. Reenable? [Y/n]: ")
if lockoutq2 == "y" or "Y" or " ":
#same as above w/ editing the lockout text
quit()
if lockoutq2 == "n" or "N":
quit()
else:
lockdownerr = raw_input("Invalid input. [2] attempts remaining. Reenable? [Y/n]: ")
if lockdownerr == "y" or "Y" or " ":
#aaa
quit()
if lockdownerr == "n" or "N":
quit()
else:
lockdownfinal = raw_input("Invalid input. [1] attempt remaining. Reenable? [Y/n]: ")
if lockdownerr == "y" or "Y" or " ":
#aaa
quit()
if lockdownerr == "n" or "N":
quit()
else:
print "Invalid input. Enabling anyway."
#you get the point
quit()
this is where I want the code to read ".Verify.txt" and use its content as the passkey
这是我希望代码读取“ .Verify.txt”并将其内容用作密码的地方
I suggest you start with a much smaller example eg 我建议您从一个小得多的例子开始,例如
verify1 = raw_input("Please enter verification key: ")
passkey = open(".Verify.txt").read().strip()
if verify1 == passkey:
print("Match")
else:
print("Not Match")
Similarly, you can open .Lockout.txt
and check its contents for lockout
同样,您可以打开
.Lockout.txt
并检查其内容以进行lockout
If you need to open a file for read/write, use "rw"
, not two variables for doing either against the same file. 如果您需要打开一个文件进行读写操作,请使用
"rw"
,而不要使用两个变量对同一个文件进行操作。
