Python- 我如何合并两个输出并合并它们以便打印出单个值？ python 2.7

Question

所以基本上我有这个代码：

try:
    fhanddate = open('AAPLprice.txt')

except:
    print 'Could not open file - closing application'
    exit()

stock_date = []

for line in fhanddate:
    p = line.strip()
    q = p.split(',')
    r = q[0:]

    stock_date.append(r)

for line in stock_date:
    pass
last = line
print last[0]

try:
    fhanda = open('AAPLprice.txt')
except:
    print 'Could not open file - closing application'
    exit()

stock_priceA = []

for line in fhanda:
    p = line.strip()
    q = p.split(',')
    r = q[-1:]
    stock_priceA.append(r)

print max(stock_priceA)

我的输出结果是：

2015-07-21    
['129.606052']

所以我想知道如何组合这两个输出，结果是：2015-07-21 129.606052

当我尝试将它们组合起来时，出现 "TypeError: cannot concatenate 'str' and 'list' objects" 错误

Answer 1

您可以简单地用“+”将它们连接在一起：

a = 2015-07-21 
b = ['129.606052']
print a + b[0]

b[0] 取列表中的第一项，b。在本例中，它取出列表中的唯一项。您可以通过简单地在它们之间添加一个字符串来添加 space：

print a + " " + b[0]
