Google AI Overview
In Python, int(9.9) returns 9.
Here’s why:
The int() function truncates the decimal part of a floating-point number.
It does not round — it simply drops everything after the decimal point.
So 9.9 becomes 9.
In Python, any nonzero number (whether int, float, or complex) evaluates to True when converted to bool.
In Python, int and Decimal are both numeric types, but they serve very different purposes: int is for whole numbers, while Decimal is for precise decimal arithmetic, often used in finance or scientific contexts.
When you run bytes(4) in Python, it creates a bytes object of length 4, filled with zeros.
b = bytes(4)
print(b) # b'\x00\x00\x00\x00'
''' ... ''' or """ ... """) creates a multi‑line string.在微距拍攝中通常不需要使用大光圈，因為即使在中小光圈下，景深已經非常淺。在 1:1 放大倍率下，即使使用 f/8–f/11，景深也只有幾毫米。若用大光圈 (f/2.8–f/4)，景深可能縮到不到 1 毫米，導致昆蟲的眼睛清晰但觸角完全模糊。大光圈下焦點範圍極窄，任何微小晃動或主體移動都會失焦。若使用小光圈 (如 f/16)，光線較少，需要額外補光或使用閃燈。這也是為什麼常見的工作光圈範圍在 f/8–f/11。
標準鏡頭即使靠近拍攝，放大倍率通常不足 1:1，景深相對較深，因此不需要像微距那樣擔心「極淺景深」。在標準鏡頭特寫中，使用大光圈 (f/1.8–f/2.8) 仍能創造淺景深效果，讓背景柔和模糊。但因為放大倍率不高，景深不會像微距那樣縮到幾乎不可用，焦點範圍仍有一定寬度。

In Python, the expression int(hexNum, 16) means “convert a hexadecimal string into a decimal integer.”
Curly brackets: dictionaries
In Python, def is the keyword used to define a function.
In Python, a for loop is used to repeat a block of code for each item in a sequence (like a list, tuple, string, or range).
for variable in sequence:
# code block
variable → takes each value from the sequence one by one.
sequence → the collection you want to loop through.
The code block runs once for each item.
In Python, char isn’t a separate data type like in some other languages (for example, C or Java).
def check_number(n):
if n > 0:
return "Positive"
elif n == 0:
return "Zero"
else:
return "Negative"
print(check_number(5)) # Positive
print(check_number(0)) # Zero
print(check_number(-3)) # Negative
== is the equality operator. It’s used to check whether two values are equal.
