## Python: How to integrate a math function using only math module?

Any of those help Just started learning python, and was asked to define a python function that integrate a math function. , Let's say your integration function looks like this:
code :
``````def integrate(func, lo_x, hi_x):
#... Stuff to perform the integral, which will need to evaluate
# the passed function for various values of x, like this
y = func(x)
#... more stuff
return value
``````
``````value = integrate(lambda x: 2 * x + 3, 1, 2)
``````

## My python calculator is returning a string and not the correct sequence of math operations

With these it helps This is because all values that input() captures are strings. You need to convert the values to numbers, (integers int() in this case) before performing your calculations.
code :
``````x = int( input("Enter the first number. ") )
y = int( input("Enter the second number. ") )
``````
``````if choice == "1" or choice == "add":
``````
``````if choice == "1" or "add": # always True because 'add' is a non-empty string
``````
``````if 'add':
``````

## Python calculator with the math.sqrt function

like below fixes the issue You convert the operator to upper case but the elif has lower case 'sqrt'.
Change it to
code :
``````elif (operator) == "SQRT":
result = math.sqrt(no1)
``````

## Trying to build a simple calculator in Python can't manage to iterate between math symbols

Hope this helps I think Georgy was correct and this is very similar to the answer they linked to above. However, you have a few other issues that you might be running into that might be confusing you. I think what you are looking for is something similar to this:
code :
``````# take operand
print('Select operator')
while True:
operator = str(input('Choose between + or * or - or /'))
if operator in ("+", "*", "-", "/"):
break
else:
print('error')
continue

print(operator)
``````

## Beginner at Python, math functions for a simple calculator program

To fix this issue I would recommend choosing a different variable name within your function as it can be confusing to have a function and variable with the same name. You can choose to print from within the function, or you can return a value, and then print the returned value outside of the function.
