我有一个包含字符串的元组的元组:
T1 = (('13', '17', '18', '21', '32'),
('07', '11', '13', '14', '28'),
('01', '05', '06', '08', '15', '16'))
我想把所有的字符串元素转换成整数，并把它们放回一个列表的列表:
T2 = [[13, 17, 18, 21, 32],
[7, 11, 13, 14, 28],
[1, 5, 6, 8, 15, 16]]

转换 str -> int 转换列表[str] ->列表[int]
当前回答
只使用列表推导式:
[[int(y) for y in x] for x in T1]
其他回答
使用列表推导式:
t2 = [map(int, list(l)) for l in t1]
只使用列表推导式:
[[int(y) for y in x] for x in T1]
在Python 3.5.1中，类似这样的工作:
c = input('Enter number:')
print (int(float(c)))
print (round(float(c)))
and
Enter number: 4.7

T3=[]
for i in range(0,len(T1)):
T3.append([])
for j in range(0,len(T1[i])):
b=int(T1[i][j])
T3[i].append(b)
print T3
你可以这样做:
T1 = (('13', '17', '18', '21', '32'),
('07', '11', '13', '14', '28'),
('01', '05', '06', '08', '15', '16'))
new_list = list(list(int(a) for a in b if a.isdigit()) for b in T1)
print(new_list)
