string to int python code example

Example 1: check if string can be converted to int python

# CHECKING IF INT
variable='3'
try:
    int(variable)
    # this will execute if it is integer
    print('You typed an int')
except ValueError:
  	# otherwise this will execute
    print('You did not type an int')

# CHECKING IF FLOAT
variable='3'
try:
    float(variable)
    print('You typed a float')
except ValueError:
    print('You did not type a float')

Example 2: python string to int

# Use the function int() to turn a string into an integer
string = '123'
integer = int(string)
integer
# Output:
# 123

Example 3: python convert string to integer in base

int(x, base=10)
>>> int('s',base=29)
28

Example 4: python get int from string

>>> import re
>>> string1 = "498results should get"
>>> int(re.search(r'\d+', string1).group())
498

Example 5: python convert string to int

# this is a string
a = "12345"
# use int() to convert to integer
b = int(a)

# if string cannot be converted to integer,
a = "This cannot be converted to an integer"
b = int(a)  # the interpreter raises ValueError

Example 6: convert string to number python

#INTEGERS
# Use the class int() to turn a string into a integer
s = "120"
s = int(s)
print(s+1)
#121
#FLOATS
# Use the class float() to turn a string into a float
s="2.5"
s = float(s)
print(s*2)
#5.0
