Because the actual situation of transaction records are often stored on the external storage, such as databases or other formats of the file, in each calculation of the candidate count will need to compare the candidate with all transactions, it is known that access to the external memory is often relatively low efficiency, so Apriori joined the so-called pruning step, The candid
questions about wrapping lines
First, ask a question, as follows.
The Python program code is as follows:
The output from the previous line of code is as follows:
I ' m Bob. What ' s your name?
The output above does not wrap. To wrap the line before what, the effect is:
I ' m Bob.What ' s your name?
What to do.
Hit the carriage return before what, OK. No, the effect of this carriage return is the statement wrapping, not the output line wrapping. solutions with line breaks

This is much like a transformer (Adapter), which transforms one voltage into another. Electricity in the United States is 110V and the voltage in China is 220V. If you want to use American electrical appliances in China, you must have a transformer that converts a 220V voltage to a 110V voltage. This tran
The monitor just opened the machine all normal, but after a while there is no grating, no image, and a slight squeak issued. From the phenomenon of failure, the display is a failure of instability. Using the cooling method and heating method to check all the main circuits of the display, the problem is found, and then the following check:

In any case, the diode throws out half the voltage of the alternating current, making the output voltage always positive or negative forever, that is, it becomes a direct current. This process is called rectification.There are two problems, after rectifying the voltage peak or 220 volts, too high, the other voltage is beating (pulsation), not go
