Python Basics

Just to summarise everything

Data Types in Python

Data Types Example
Int age = 10
date = 20
year = 2022
Float weight = 60.5
String name = "Vishal"
output = "Vishal\'s age"
movie = 'Brahmastra'
Boolean is_it_day = True
lights = False
List all_subjects = ["English", "Hindi", "Maths", "Science"]
print(all_subjects[1])

Output
Hindi

Dictionaries result={"English":57, "Hindi":80, "Maths":99, "Science":89}
print(result["English"])

Output
57

List Functions

Function Syntax Example
Append list.append() all_subjects.append("Sanskrit")
Insert list.insert(position, "value") all_subjects.insert(2,"Social Science")
Delete del(list[index]) del(all_subjects[2])

 

For Loop with List in Python

Code

all_subjects = ["English", "Hindi", "Maths", "Science"]

for subject in all_subjects:
 print(subject)

 

Output

English
Hindi
Maths
Science

If Else in Python

 

Code

light_is_on = True

if light_is_on :
  print("Light is On")
else:
  print("Light is Off")

 

Output:
Light is On
