pyhton 去掉字符串前边的u''

for i in range(len(colnames)):    print type(rowData[i])    if type(rowData[i]) == float :#如果是字符串类型，则进行编码      print colnames[i]      eachRowData[colnames[i].encode('ascii')] = rowData[i]          #.encode('raw_unicode_escape')    elif type(rowData[i]) == unicode:        eachRowData[colnames[i].encode('ascii')] = rowData[i].encode('ascii')list.append(eachRowData)

其实就在字符串后边加一个
.encode('ascii')就行啦
