我写了一个这样的文件:
try
add app.scss
.alertCustomCss {
color: #e37b26; // text color for basic alerts
button {
color: white !important;
background-color: color($colors, primary, base) !important;
}
.alert-message {
color: #e37b26; // text color for confirm alerts
// background-color: color($colors, primary, base) !important;
}
.alert-sub-title {
color: #e37b26; // text color for confirm alerts
// background-color: color($colors, primary, base) !important;
}
.alert-wrapper {
background-color: color($colors, gray, base);
}
.alert-input {
color: black;
}
}
预期结果是:
import numpy as np
rx = np.zeros((2,2))
rx2 = rx
rx2[0][1]=1
print(rx)
print(rx2)
但是当我运行这段代码时,我得到了:
[[0. 0.]
[0. 0.]]
[[0. 1.]
[0. 0.]]
为什么以及如何?
答案 0 :(得分:1)
import numpy as np
rx = np.zeros((2,2))
rx2 = rx.copy()
rx2[0][1]=1
print(rx)
print(rx2)
结果
[[0. 0.]
[0. 0.]]
[[0. 1.]
[0. 0.]]
