python add string and int

# To combine an str and int you need to convert the int to a str first.
# You can do this all on one line however like so. Just keep adding plus signs between statements:
string = 'Hello there ' + str(your_variable1_here) + ' oh my more text ' + str(your_variable2_here)

# Working example that makes sure all items in a list are strings:
list = ['hello', 'howdy', 73, 'greetings']
for i, c in enumerate(list):
    assert isinstance(c, str), 'List index ' + str(i) + ' was invalid! ' + '(It's value is: ' + str(c) + ')'

# Will output this error because '73' is an INT object and not a STR object:
# AssertionError: List index 2 was not valid! (73)

adding integers from a string python

#prints the sum of any number 
def sum_of_digits(nums: int):
    nums=str(nums)
    sum = 0
    for i in nums:
        sum+=int(i)
    return sum

print(sum_of_digits(123))

#prints '6'. 1+2+3

append string variable with integer python

string = 'string'
for i in range(11):
    string += 'i'
print string
# It will print string 012345678910.

add string to integer in python

a = '123' # This is a string
b = 'love' # This is a string
c = 456 # This is an integer
# 'a' can be converted to an integer but 'b' cannot
print(c + int(a)) # Output - 579
print(c + int(b)) # This will give a Value Error
