Still struggling with this code (if block seems to work, but does not match the gender and as such goes to unknown.

]if gender.lower == "m" or gender.lower == "male":
    print("M You require " + bmr_man + " Calories just to maintain your current body weight ")
elif gender.lower == "f": # or gender.lower == "female":
    print("F You require " + bmr_woman + " Calories just to maintain your current body weight ")   
else: print("Your BMR is: Unknown")

# Purpose - Basal Metabolic Rate -


# Get Age & store in a variable
age = int(input("What is your age in years ? "))

# Get persons Gender
gender = input("Are you m or f ? ") # inputs are already a string so no need to coerce. 

# get weight kgs and store
weight = float(input("What is your weight in Kilo's ? "))

# Get height bmi_target = int(input("what is your target BMI"))
height = float(input("What is your height in metres? (Example 1.75 ) "))

# calculate BMR here and store in a variable
bmr_man = (10 * weight) + 6.25 * height - (5 * age) + 5
bmr_woman = (10 * weight) + (6.25 * height) - (5 * age) + 161

# Round the BMI result down to 0 decimal place
bmr_man = str(round(bmr_man))
bmr_woman = str(round(bmr_woman))

# calculate BMI here and store in a variable
bmi = (weight / height) / height

# Round the BMI result down to 1 decimal place
bmi = str(round(bmi))   # This was the original ** bmi = str(round(bmi), 1) the output exaple was 29.9 and the .9 was of no use


print() # adds a blank line to aid formating
print("This is just test code to prove the variables are being populated") # adds a blank line to aid formating
