Python formart()

name = "xnocode"
age = 25
 
print("My name is {} and age is {}".format(name, age))

output

My name is xnocode and age is 25

Note

• f-string is fastest and easiest
• format() is older method
• Use f-string in modern Python

• Index-Based Formatting

Used to insert values into specific positions using indexes.

example

name = "xnocode"
age = 25
 
print("My name is {0} and age is {1}".format(name, age))

output

My name is xnocode and age is 25

• changing order

name = "xnocode"
age = 25
 
print("Age is {1} and name is {0}".format(name, age))

output

Age is 25 and name is xnocode

Syntax:
"{index}".format(values)

Note

• Index starts from 0
• You can reuse values multiple times
• Useful when order needs to change

• Value-Based Formatting

Used to insert values using names (keys) instead of index.

example

name = "xnocode"
age = 25
 
print("My name is {name} and age is {age}".format(name=name, age=age))

output

My name is xnocode and age is 25

• different order

name = "xnocode"
age = 25
 
print("Age is {age} and name is {name}".format(name=name, age=age))

output

Age is 25 and name is xnocode

Syntax:
"{key}".format(key=value)

Note

• More readable than index-based
• Order does not matter
• Recommended when multiple values are used
