1
So, how do you know the logic of tracing and how to build this logic?
2
We will do this in our session.
3
What is the output of this program?
4
We will do this in our session.
5
What is the range of the function?
6
How does the print function work?
7
These are two basic questions.
8
We will do this in our session.
9
Suppose we have a range of functions.
10
What is the range function?
11
If we have the range function, one number is one, the other number is five.
12
When we have range function, we have to generate value.
13
Then, we have to generate range function one, two, three and four.
14
So, the list is generated.
15
We will mention the number.
16
1,5 is 4.
17
The last number is excluded.
18
The range function is the general syntax.
19
The range function is the start value, the end value, and the step count.
20
The step count is not the same.
21
Because by default, the step count to 1 is considered.
22
I have the first value increase.
23
So if you have a range function,
24
range 2,10,3, then you have a range function output.
25
In that case, you have two numbers to start.
26
So if you have three steps count, you have to have a number of 3.
27
5 number is 5 and plus 3 and plus 3
28
and plus 3 and plus 3 and plus 11 value is 10
29
and cross so we don't add that number is the same as we have to generate the range function
30
the range function is negative range descending order the meaning is 10,
31
here is 5, minus 1 and the value is less than 10,
32
9, 8, 7, 6 and 5.
33
5 minutes and 9 minutes, last number exclude.
34
Range function general also work.
35
So, we need to trace the program to make some of the way.
36
So, we need to trace the range of the program the the the the
37
the
38
the
39
print function use and print is high string print
40
and the other print function is by value then we have the output here
41
but we have two statement here and the other line is by the
42
problem
43
the problem
44
the problem the
45
problem
46
end statement to space by default in every print function newline character inserted end
47
or constant end or character sequence slash in slash in remove and put a newline and same line
48
previous print means that end then alter character So, this is the case of the program.
49
So, we have to understand the case of this program.
50
So, we will have to do actual tracing.
51
So, for I in range, 1,4.
52
So, what is the range?
53
I have to do 1,4.
54
I have to read the step count.
55
So, I have to do 1,2,3.
56
But what do we think?
57
For i in range, i in range is 1,4.
58
This meaning is that i has a variable, and the range means a value point.
59
I can say that i is 1,4.
60
I can say that i is 1,4.
61
The value is the point that I just put on the loop chart.
62
The loop is the loop.
63
The loop is the loop.
64
The loop is the loop for indent.
65
The loop is the loop.
66
It must be parallel.
67
। foreign
68
foreign foreign foreign
69
like this one.
70
If we find this one, we can print this one.
71
So, we print this one.
72
We turn this one side but there is a whole purpose that you can always trace the pen paper.
73
but if you can find the end statement, you can find the end statement by default, remove the card and you can find the end statement.
74
that one statement will find a point in the end statement, this statement is a print and this statement is not a print,
75
but when you see the range in the same year, you can check the JLA value to the point.
76
But it is not, JLA point to the point is that the loop is not a term.
77
Why is the loop in the loop?
78
The range is not a print.
79
The loop is not a print.
80
I will print the same as you have a cursor in the same line.
81
By default, this is the end is equal to slash and then I will print the next line.
82
I will print the same as this is important.
83
What is the statement?
84
It is not simple, it is not simple.
85
It is parallel.
86
What is the statement?
87
It is the same as I look.
88
I will check the
89
value of 2.
90
I will point the value of 2.
91
2 point the value of 2.
92
J in range 1, I plus 1.
93
I will range.
94
J in range 1, I value of 2.
95
2 plus 1 is 3.
96
1,3 and step count is 1 in this case j is valued 1 and 2 j is generated 1 and 2.
97
j in range 1,2 is 80 j is 1 point to 1.
98
j is 1.
99
j is 1.
100
I will point to the other one.
101
Yes, I will.
102
Three.
103
I will.
104
Next time, range.
105
Range.
106
1, 4, 1.
107
In this case, 1, 2, and 3.
108
This is the three values.
109
I will point to the other one.
110
I will point to the other one.
111
I will point to the other one.
112
I will point to the other one foreign foreign
113
It is not normal range.
114
So, the output is the same.
115
The idea is wrong.
116
What is the exact process?
117
The process is not very important.
118
If you have a logic build, then you will need to build the tracing.
119
We are going to do all the tutorials in logic building.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
