我有一个包含以下内容的CSV文件.
I have a CSV file containing the following.

0.00016,0.000223,0.000011,0.000142
0.008853,0.006519,0.002043,0.009819
0.002076,0.001686,0.000959,0.003107
0.000599,0.000133,0.000113,0.000466
0.002264,0.001927,0.00079,0.003815
0.002761,0.00288,0.001261,0.006851
0.000723,0.000617,0.000794,0.002189
我想将这些值转换为Python中的数组并保持相同的顺序(行和列).我怎样才能做到这一点?

推荐答案
您应使用 csv
模块:
You should use the csv
module:
import csv
results = []
with open("input.csv") as csvfile:
reader = csv.reader(csvfile, quoting=csv.QUOTE_NONNUMERIC) # change contents to floats
for row in reader: # each row is a list
results.append(row)
这给出了:
[[0.000264, 0.000352, 8.7e-05, 0.000549],
[0.00016, 0.000223, 1.1e-05, 0.000142],
[0.008853, 0.006519, 0.002043, 0.009819],
[0.002076, 0.001686, 0.000959, 0.003107],
[0.000599, 0.000133, 0.000113, 0.000466],
[0.002264, 0.001927, 0.00079, 0.003815],
[0.002761, 0.00288, 0.001261, 0.006851],
[0.000723, 0.000617, 0.000794, 0.002189]]
