Question

我有一个编程任务，但我无法弄清楚如何解决这个输出问题。

这是我的输出：

[['Choc 5\t'], ['Vani 10'], ['Stra 7'], ['Choc 3 '], ['Stra 4']]

但它应该是这样的：

['Choc', 5], ['Vani', 10], ['Stra', 7], ['Choc', 3], ['Stra', 4]]

代码：

def process_input(lst):
    result = list(map(lambda x: [x[0:7]], lst))
    return result

string = input()
lines = []
while string != "END":
    lines.append(string)
    string = input()
print(process_input(lines))

Answer 1

output = [['Choc 5\t'], ['Vani 10'], ['Stra 7'], ['Choc 3 '], ['Stra 4']]
print(output)
output = [[s[0].strip().split(' ')[0], int(s[0].strip().split(' ')[1])] for s in a]
print(output)

输出

[['Choc 5\t'], ['Vani 10'], ['Stra 7'], ['Choc 3 '], ['Stra 4']]
[['Choc', 5], ['Vani', 10], ['Stra', 7], ['Choc', 3], ['Stra', 4]]

Answer 2

您可以尝试这种方法：

data=[['Choc 5\t'], ['Vani 10'], ['Stra 7'], ['Choc 3 '], ['Stra 4']]

print(list(map(lambda x:[x[0].split()[0] , int(x[0].split()[1])],data)))

输出：

[['Choc', 5], ['Vani', 10], ['Stra', 7], ['Choc', 3], ['Stra', 4]]
