python 问题
>>> counter = 0
>>> miles = 1000.0
>>> name = 'Bob'
>>> counter = counter + 1
>>> kilometers = 1,609 * miles
>>> print '%f miles is the same as &f km' % (miles, kilometers)
Traceback (most recent call last):
File "", line 1, in
print '%f miles is the same as &f km' % (miles, kilometers)
TypeError: not all arguments converted during string formatting
怎么回事?
? 有什么不同?

print '%f miles is the same as %f km' % (miles, kilometers)

counter&=0x0f;是什么意思? Python中+=是什么意思 P0=counter&0x0f怎么理解 python组合问题有一个二维数列list=[['a','b'],['c','d','e'],'f',['g','h', 在python 中is和= = 的区别 Python中 d1 = lambda:random.uniform(-volatility,volatility) 这 python中的语句 prefix = re.sub(r'\.[^/]*$',' ',imagefile) 解释 if(counter==0&&Re_buf[0]!=0x55) return;是什么意思? 有关PYTHON计算问题 a few miles to the south of London= a few miles south to Lon 有关PYTHON的计算问题【Python】程序问题,求大神
