right of the location parameter; The default parameter should usually be defined as an immutable type def test(x,y=2): print(x) print(y)test(1)test(1,3)test(1,y=1)4. Variable length parameters Variable length refers to the number of arguments is not fixed, and the actual parameters are defined by position and by the keyword, for the two forms of variable length, formal parameters corresponding to two solutions to the complete storage of them, respectively, *args,**kwargs

In the previous article, we queried the fabric network by executing node query.js, and returned 10 vehicles of information: #node Query.js The output from the command line is as follows: This is 10 cars. The black Tesla model owned by Adriana, the red Ford Mustang owned by Brad, was owned by the man named Pari violet Fiat Punto and so on. The ledger is based on key/value, and in this implementation, the key values are from CAR0 to CAR9. This will b

, why ah, the programmer can afford it.There is a question on the water and wood. "Why is it so low?" "User God reply" There is a place, called the programmer can not get to the place. ” Of course, programmers are not so keen on buying a house, the house price is the programmer's wife or programmer's mother buy high, not related to the programmer. What programmers love to buy. Nature is different. Others buy Land Rover to buy BMW, they buy Tesla. O

of AI and generate faster, more reliable answers.2) Learning AI (machine learning ai)Machine learning (ML) AI is the kind of artificial intelligence that can automatically drive your Tesla on a freeway. It is also at the forefront of computer science, but it is expected to have a great impact on everyday workplaces. Machine learning is to look for "patterns" in big data and then use these patterns to predict results without too much human explanation

an object. The acceleration of motion is also changed, and if the acceleration is taken, what force the object is subjected to or what kind of motion the object carries out, we can know. Using acceleration, we can do the simulation of pedometer, object motion application. the 3 elements of the values variable of the accelerometer are represented by X,Y , respectively. , Z the acceleration value of the axis. the gravity sensor uses the same set of coordinate systems as the accelerometer sensor

./smemSquare The results on Tesla K40c (4-byte mode) are as follows: ./smemSquare at device 0 of Tesla K40c with Bank Mode:4-byte Then, use the two parameters below nvprof to measure the corresponding bank-conflict: Shared_load_transactions_per_request Shared_store_transactions_per_request The result is as follows. row-major only has one transaction: Kernel:setColReadCol (int*)1 shared_load_transactions_pe

negative x-axis.Tilt the phone upward and the y-axis is negative.Tilt the phone downward and the y-axis is positive.The accelerometer is probably the most sophisticated MEMS product, with a wide range of accelerometer sensors on the market.The commonly used accelerometer in mobile phones is Bosch's BMA series, AMK 897X series, St's LIS3X series, etc.These sensors typically provide an acceleration measurement range from ±2g to ±16g with an I²C or SPI interface connected to the MCU with a data ac

environmental magnetic field data of the X, Y, andz axes. The unit of the value is micro-Tesla (Micro-tesla), expressed in UT . The unit can also be Gauss (Gauss),1tesla=10000gauss. There is generally no independent magnetic sensor on the hardware, and the magnetic data is provided by the electronic Compass sensor (e-compass). The Electronic Compass sensor also provides direction sensor data for the follow

the phone to the left, and the X axis is positive. Tilt the phone to the right, and the X axis is negative. Tilt the phone up. the Y axis is negative. Tilt the phone down, and the Y axis is positive. Acceleration sensors may be the most mature mems product. There are many types of acceleration sensors on the market. Commonly used acceleration sensors in mobile phones include BOSCH (BOSCH) BMA series, AMK 897X series, and ST LIS3X series. These sensors generally provide an acceleration measurem
