The names of the variables arecase sensitive. So, the variable that you create with lower case is not the same variable that is created with upper case. As an example, a and A are two different variables in python programming. You can learn alsoPython Lambda Function Now, to see how to...
Python allows you to assign values to multiple variables in one line: ExampleGet your own Python Server x, y, z ="Orange","Banana","Cherry" print(x) print(y) print(z) Try it Yourself » Note:Make sure the number of variables matches the number of values, or else you will get an...
import tensorflow as tf # 创建一个变量 var = tf.Variable(1.0, name='my_variable') # 定义一个assign操作,将变量的值更新为2.0 update_var = var.assign(2.0) # 初始化所有变量 init = tf.global_variables_initializer() with tf.Session() as sess: sess.run(init) print(sess.run(var)) ...

init = tf.global_variables_initializer(). 创建会话并运行操作。 with tf.Session() as sess: sess.run(init). 执行赋值相加操作。 result = sess.run(assign_op). print("操作后的变量值:", result)。 在上述代码中,首先创建了一个可训练的变量`var`,然后定义了一个常量`add_value`,接着使用`assign...
