Python | Convert location coordinates to tuple

Sometimes, while working with locations, we need a lot of data which has location points in form of latitutes and longitudes. These can be in form of a string and we desire to get tuple versions of same. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using tuple() + float() + split() + map()

The combination of above functions can be used to perform this task. In this, we first split the two parts of coordinates into a list, apply float function to each of them using float() and map() and lastly it is converted to tuple using tuple().

# Python3 code to demonstrate working of 
# Convert location coordinates to tuple 
# Using tuple() + float() + split() + map() 
  
# Initializing string 
test_str = "44.6463, -49.583"
  
# printing original string 
print("The original string is : " + str(test_str)) 
  
# Convert location coordinates to tuple 
# Using tuple() + float() + split() + map() 
res = tuple(map(float, test_str.split(', '))) 
  
# printing result 
print("The coordinates after conversion to tuple are : " + str(res)) 

Output :

The original string is : 44.6463, -49.583
The coordinates after conversion to tuple are : (44.6463, -49.583)

Method #2 : Using eval()
This is the one-liner and recommended method to perform this particular task. In this, the eval(), internally detects the string and converts to floating point number seperated as tuple elements.

# Python3 code to demonstrate working of 
# Convert location coordinates to tuple 
# Using eval() 
  
# Initializing string 
test_str = "44.6463, -49.583"
  
# printing original string 
print("The original string is : " + str(test_str)) 
  
# Convert location coordinates to tuple 
# Using eval() 
res = eval(test_str) 
  
# printing result 
print("The coordinates after conversion to tuple are : " + str(res)) 

Output :

The original string is : 44.6463, -49.583
The coordinates after conversion to tuple are : (44.6463, -49.583)
