在:How to write numpy arrays to .txt file, starting at a certain line?
人们帮助我解决了我的问题 - 这适用于numpy 1.7或更高版本。不幸的是,我必须使用1.6版本 - 以下代码(谢谢@Praveen)
extra_text = 'Answer to life, the universe and everything = 42'
header = '# Filexy\n# time operation1 operation2\n' + extra_text
np.savetxt('example.txt', np.c_[time, operation1, operation2],
header=header, fmt='%d', delimiter='\t', comments=''
给我一个错误的numpy 1.6
numpy.savetxt() got an unexpected keyword argument 'header' · Issue ...
是否有针对版本1.6的解决方法产生相同的结果:
# Filexy
# time operation1 operation2
Answer to life, the universe and everything = 42
0 12 100
60 23 123
120 68 203
180 26 301
答案 0 :(得分:2)
首先编写标题,然后转储数据。
请注意,您需要在标题的每一行添加#
,因为np.savetxt
不会这样做。
time = np.array([0,60,120,180])
operation1 = np.array([12,23,68,26])
operation2 = np.array([100,123,203,301])
header='#Filexy\n#time operation1 operation2'
with open('example.txt', 'w') as f:
f.write(header)
np.savetxt(f, np.c_[time, operation1, operation2],
fmt='%d',
delimiter='\t')
