Variable

  • विशिष्ट, case-sensitive नाम

  • वैरिएबल नाम से value बुलाएँ

  • 1.79 m - 68.7 kg

height = 1.79
weight = 68.7

height
1.79
Python परिचय

BMI निकालें

height = 1.79
weight = 68.7

height
1.79

$$ \text{BMI} = \frac{\text{weight}}{\text{height}^2} $$

68.7 / 1.79 ** 2
21.4413
weight / height ** 2
21.4413
bmi = weight / height ** 2
bmi
21.4413
Python परिचय

Reproducibility

height = 1.79
weight = 68.7
bmi = weight / height ** 2
print(bmi)
21.4413
Python परिचय

Reproducibility

height = 1.79
weight = 74.2 # <-
bmi = weight / height ** 2
print(bmi)
23.1578

day_of_week = 5
type(day_of_week)
int

Python Types (2)

x = "body mass index"
y = 'this works too'

type(y)
str
z = True
type(z)
bool

Python Types (3)

2 + 3
5
'ab' + 'cd'
'abcd'
  • अलग type = अलग behavior!
