所以 Python 脚本会得到这个数据:
6.1900E+03 1.97899E-06 0.0066
7.4300E+03 2.03105E-06 0.0070

1.8900E+04 1.58478E-06 0.0107
2.1700E+04 1.09529E-06 0.0133
2.4900E+04 6.59218E-07 0.0173
2.8500E+04 3.19703E-07 0.0250
3.2500E+04 1.55052E-07 0.0358
3.7000E+04 6.94320E-08 0.0542
4.2100E+04 3.44175E-08 0.0764
4.7800E+04 2.37904E-08 0.0944
5.4200E+04 1.29016E-08 0.1283
6.1400E+04 5.45355E-09 0.1770
6.9500E+04 4.18030E-09 0.2486
7.8700E+04 2.47747E-09 0.2629
8.8900E+04 2.69887E-09 0.2820
1.0100E+05 2.15937E-09 0.4286
1.1300E+05 4.39994E-10 0.7824
1.2800E+05 0.00000E+00 0.0000
1.4400E+05 0.00000E+00 0.0000
1.6300E+05 0.00000E+00 0.0000
1.8300E+05 0.00000E+00 0.0000
2.0700E+05 0.00000E+00 0.0000
2.3300E+05 0.00000E+00 0.0000
2.6300E+05 0.00000E+00 0.0000
2.9600E+05 0.00000E+00 0.0000
然后我需要中心列的总和。
像这样: (1.97899E-06 + 2.03105E-06 + 2.08666E-06 + ... + 0.00000E+00) = 1.90994E-05
只有第二列对这个问题很重要。
第一列代表时间。第二列代表一些数据编号。第三列代表一些随机数。
请帮我找出来:((
