How does Python convert a string with only numeric characters into a int using int() function
python
Ethan Jacksonafter looking into a lecture I have encountered a small problem. I don't understand the steps or how Python converts a numeric value inside a string into a int(or even a float) using there int() or float() function.
e.g #assign a variable
x = '3'
int(h)
**Please mind the fact that I have been trying this code in the python shell and experimenting. I have also tried Python tutor to show me how Python executes this code one by one, which has not been quite descriptive.
I just wish to know how python executes this code one by one and how it converts the string into a integer** Thank you for taking the time to read this :)
Answer
x = '3'
# string to int
x_int = int(x)
print(x_int) # Output : 3
# string to float
x_flt = float(x)
print(x_flt) # Output : 3.0
# integer to float
x_flt = float(x_int)
print(x_flt) # Output : 3.0
# float to int
x_int = int(x_flt)
print(x_int) # Output : 3
# integer to string
x_str = str(x_int)
print(x_str) # Output : '3' (the quotes may not be present)
# float to string
x_str = str(x_flt)
print(x_flt) # Output: '3.0' (the quotes may not be present)
