如何在不重复数据集中的字母的情况下为大于 0 的字母制作列表？
How to make a list for letters with great than 0 without repeation for that letter from a dataset?
我有一个包含 3 列的数据集。一列有特定的字母代码（可能重复），另一列有相应的值（可以是正数或负数）。
如何同时计算大于 0 和/或小于 0 的字母，而不重复这些字母代码。
我放置了我的数据集及其外观，因为我是编程新手，也许有人可以帮助我。

我不确定您 data 的格式。如果看起来像
[[1, 'G', 360.0],
[2, 'M', -67.2],
[3, 'K', -78.0],
...
[244, 'A', -57.8],
[245, 'M', -87.0],
[246, 'K', 163.5]]
您可以执行以下操作：
pos_codes = set()
neg_codes = set()
for row in data:
if row[2] > 0:
pos_codes.add(row[1])
else:
neg_codes.add(row[1])
neg_and_pos_codes = pos_codes.intersection(neg_codes)
print('Double codes:', neg_and_pos_codes)
print('Number of double codes:', len(neg_and_pos_codes))
结果：
Double codes: {'N', 'R', 'G', 'K', 'E', 'T'}
Number of double codes: 6
或者没有显式循环的更短一点：
neg_and_pos_codes = ({row[1] for row in data if row[2] > 0}
.intersection({row[1] for row in data if row[2] < 0}))
如果 data 是按列组织的
[[1, 2, 3, ..., 244, 245, 246],
['G', 'M', 'K', ...,'A', 'M', 'K'],
[360.0, -67.2, -78.0, ..., -57.8, -87.0, 163.5]]
然后
pos_codes = set()
neg_codes = set()
for code, number in zip(data[1], data[2]):
if number > 0:
pos_codes.add(code)
else:
neg_codes.add(code)
neg_and_pos_codes = pos_codes.intersection(neg_codes)
或
neg_and_pos_codes = ({code
for code, number in zip(data[1], data[2])
if number > 0}
.intersection({code
for code, number in zip(data[1], data[2])
if number < 0}))
会产生相同的结果。

我不确定您 data 的格式。如果看起来像
[[1, 'G', 360.0],
[2, 'M', -67.2],
[3, 'K', -78.0],
...
[244, 'A', -57.8],
[245, 'M', -87.0],
[246, 'K', 163.5]]
您可以执行以下操作：
pos_codes = set()
neg_codes = set()
for row in data:
if row[2] > 0:
pos_codes.add(row[1])
else:
neg_codes.add(row[1])
neg_and_pos_codes = pos_codes.intersection(neg_codes)
print('Double codes:', neg_and_pos_codes)
print('Number of double codes:', len(neg_and_pos_codes))
结果：
Double codes: {'N', 'R', 'G', 'K', 'E', 'T'}
Number of double codes: 6
或者没有显式循环的更短一点：
neg_and_pos_codes = ({row[1] for row in data if row[2] > 0}
.intersection({row[1] for row in data if row[2] < 0}))
如果 data 是按列组织的
[[1, 2, 3, ..., 244, 245, 246],
['G', 'M', 'K', ...,'A', 'M', 'K'],
[360.0, -67.2, -78.0, ..., -57.8, -87.0, 163.5]]
然后
pos_codes = set()
neg_codes = set()
for code, number in zip(data[1], data[2]):
if number > 0:
pos_codes.add(code)
else:
neg_codes.add(code)
neg_and_pos_codes = pos_codes.intersection(neg_codes)
或
neg_and_pos_codes = ({code
for code, number in zip(data[1], data[2])
if number > 0}
.intersection({code
for code, number in zip(data[1], data[2])
if number < 0}))
会产生相同的结果。
