[英]How to convert list pairs into tuple pairs
如何通过使用简单的编程(例如for循环)将包含对的列表转换为包含元组对的列表? x,y = ...?
我的代码:
def read_numbers():
numbers = ['68,125', '113,69', '65,86', '108,149', '152,53', '78,90']
numbers.split(',')
x,y = tuple numbers
return numbers
需求输出:
[(68,125), (113,69), (65,86), (108,149), (152,53), (78,90)]
def read_numbers():
numbers = ['68,125', '113,69', '65,86', '108,149', '152,53', '78,90']
return [tuple(map(int,pair.split(','))) for pair in numbers]
通过使用嵌套列表理解来尝试此操作:
o = [tuple(int(y) for y in x.split(',')) for x in numbers]
只需使用列表理解即可。 在这里阅读更多信息!
# Pass in numbers as an argument so that it will work
# for more than 1 list.
def read_numbers(numbers):
return [tuple(int(y) for y in x.split(",")) for x in numbers]
这是列表理解的细分和解释(用注释):
[
tuple( # Convert whatever is between these parentheses into a tuple
int(y) # Make y an integer
for y in # Where y is each element in
x.split(",") # x.split(","). Where x is a string and x.split(",") is a list
# where the string is split into a list delimited by a comma.
) for x in numbers # x is each element in numbers
]
但是,如果仅对一个列表进行操作,则无需创建函数。
尝试这个 :
def read_numbers():
numbers = ['68,125', '113,69', '65,86', '108,149', '152,53', '78,90']
final_list = []
[final_list.append(tuple(int(test_str) for test_str in number.split(','))) for number in numbers]
return final_list
