The problem seems to come from this line: d.str().

问题似乎来自这一行:d.str()。

Conversion to a string is done with the builtin str() function, which basically calls the __str__() method of its parameter.

转换到字符串是通过builtin str()函数完成的，该函数基本上调用其参数的__str__()方法。

Also, it shouldn't be necessary to call pow(). Try using the ** operator.

而且，也不需要调用pow()。尝试使用**操作符。

There is not typecast and no type coercion in Python. You have to convert your variable in an explicit way.

在Python中没有类型转换，也没有类型强制。你必须明确地转换你的变量。

To convert an object in string you use the str() function. It works with any object that has a method called __str__() defined. In fact

要在字符串中转换对象，可以使用str()函数。它适用于任何有被定义为__str__()方法的对象。事实上

str(a)

is equivalent to

相当于

a.__str__()

The same if you want to convert something to int, float, etc.

同样的，如果你想转换一些东西到int, float等。

a = 2

You can use str(a) which gives you a string object of int(2).

您可以使用str(a)来提供int(2)的字符串对象。

To manage non-integer inputs:

管理非整数输入:

number = raw_input()
try:
    value = int(number)
except ValueError:
    value = 0

Ok, if I take your latest code and rewrite a bit to get it working with Python:

好的，如果我把你的最新代码重写一遍，让它与Python一起工作:

t=raw_input()
c=[]
for j in range(0,int(t)):
    n=raw_input()
    a=[]
    a,b= (int(i) for i in n.split(' '))
    d=pow(a,b)
    d2=str(d)
    c.append(d2[0])
for j in c:
    print j

It gives me something like:

它给了我一些类似的东西:

>>> 2
>>> 8 2
>>> 2 3
6
8

Which is the first characters of the string result pow(a,b). What are we trying to do here?

这是字符串结果pow(a,b)的第一个字符。我们要在这里做什么?

>>> i = 5
>>> s = str(5)
>>> print "Hello, world the number is " + s
Hello, world the number is 5

The most decent way in my opinion is ``.

在我看来，最体面的方式是“”。

i = 32   -->    `i` == '32'

Can use %s or .format

可以使用%s或.format ?

>>> "%s" % 10
'10'
>>>

(OR)

(或)

>>> '{}'.format(10)
'10'
>>>

For someone who wants to convert int to string in specific digits, below method is recommended.

对于希望将int转换为特定数字的字符串的人，建议使用下面的方法。
