creating dynamic variable in python
for i in range(0, 9):
globals()[f"my_variable{i}"] = f"Hello from variable number {i}!"
print(my_variable3)
# Hello from variable number 3!creating dynamic variable in python
for i in range(0, 9):
globals()[f"my_variable{i}"] = f"Hello from variable number {i}!"
print(my_variable3)
# Hello from variable number 3!Dynamic Variable declaration in Python
#1st example
user_input = raw_input("Enter a variable name : ")
Enter a variable name: number
globals()[user_input] = 25
# you can use locals to assign local variable
# This is dynmic variable declaration
#2nd example
Class Table:
def __init__(self,x,y,datalist):# here x and y are no. of rows and column and datalist is 2d list
for i in range (x):
for j in range (y):
var = f'table{i}_{j}'
locals()[var] = datalist[i][j]
# here we extracted data from a list of variable length and assigned them to different variable
# this can be helpful in many situationscan we make dynamic variable in pytohn?
# Yes, globals() gives excess to all the global variables.
# globals() is a dictionary that has 'variable' : 'value' as key, value pairs...
# You may use something like
for i in range(100):
globals()['variableno_{1}'.format(i)] = "My name is variableno_{1}".format(i)
# this loop creates 100 different variable in global scope same like assigning...
# variableno_0 = "My name is variableno_1"
# variableno_1 = "My name is variableno_2"
# variableno_2 = "My name is variableno_3"
....
....
# variableno_97 = "My name is variableno_97"
# variableno_98 = "My name is variableno_98"
# variableno_99 = "My name is variableno_99"Copyright © 2021 Codeinu
