我知道使用
getpass.getuser()命令,我可以获取用户名,但是如何自动在以下脚本中实现呢？所以我希望python找到用户名,然后在下面的脚本中实现它.
脚本: os.path.join('..','Documents and Settings','USERNAME','Desktop'))
(正在使用Python版本2.7)
在Firefox中,使用Imacros,我想从批处理文件中启动多个宏,但问题是:我希望它们逐个运行.
因此,首先"宏1"将在完成后运行,"宏2"将运行,依此类推,直到"宏7".
我的批次代码:
cd C:\Program Files\Mozilla Firefox
start firefox.exe
ping -n 05 127.0.0.1>nul
start firefox.exe imacros://run/?m=NAMEofMACRO.iim
Imacros VERSION BUILD=7601105
我有一个数组,下面是重复的字符串.我想找到并替换这些字符串,但每次匹配时我都想更改替换字符串的值.
让我来证明一下.
此样本数组:
SampleArray = ['champ', 'king', 'king', 'mak', 'mak', 'mak']
应该改为:
SampleArray = ['champ', 'king1', 'king2', 'mak1', 'mak2', 'mak3']
如何使这成为可能？我已经在这3天了,没有运气.提前致谢.
My Failed Code:
import os, collections, re
SampleArray = ['champ', 'king', 'king', 'mak', 'mak', 'mak']
dupes = [x for x, y in collections.Counter(SampleArray).items() if y > 1]
length = len(dupes)
count = 0
while count < length:
j = 0
instances = SampleArray.count(dupes[count])
while j < instances:
re.sub(dupes[count], dupes[count] + j, SampleArray, j)
j += 1
count += 1 …有人可以向我解释我的代码有什么问题吗？我收到以下错误:
回溯(最近一次调用最后一次):
文件"C:\ LineRep.py",第15行,在模块中:
对于File2中的行:
ValueError:对已关闭文件的I/O操作
我的代码:
import os, Tkinter, tkFileDialog
root = Tkinter.Tk()
root.withdraw()
dirprompt = tkFileDialog.askopenfilename()
File = open (dirprompt, 'r')
File2 = open (dirprompt + 'temp', 'w')
for line in File:
File2.write(line.replace(',', ' '))
File.close()
File2.close()
names = []
for line in File2:
names.append(line)
print names
在下面的Perl程序中,由于某种原因,整数除法不会发生.相反,控制台输出两个整数的连接,也不会发生divsion的if语句.为什么是这样？谢谢.
码:
print "Please Enter Your First Number\n";
$num1 = <>; chomp $num1;
print "Please Enter Your Operation\n";
$operation = <>; chomp $operation;
print "Please Enter Your Second Number\n";
$num2 = <>; chomp $num2;
if ($operation == "+"){
$result = $num1 + $num2;
} elsif ($operation == "-"){
$result = $num1 - $num2;
} elsif ($operation == "*"){
$result = $num1 * $num2;
#Problem HERE:
} elsif ($operation == "/"){
if ($num2 == 0){
print "Cant Divide be Zero Mate\n"; …所以我试图解析一个巨大的文件，而下面的代码解析时间太长。文件大小为 2GB。我希望有人能帮助我加快速度。
import os, shlex
