int to string
It was written in the above book that when using int (), an error occurs in the description of the exponential format such as ʻint ('1e3') `(@ No.733 / 12833).
I've tried.
int_func_170120.py
ival1=int('1000')
print(ival1)
ival2=int('1e3')
print(ival2)
result
$ python int_func_170120.py
1000
Traceback (most recent call last):
File "int_func_170120.py", line 3, in <module>
ival2=int('1e3')
ValueError: invalid literal for int() with base 10: '1e3'
string to int
What I was curious about when doing the above was what if the 1e3 was converted to str.
I've tried.
str_func_170120.py
str1=str(1000)
print(str1)
str2=str(1e3)
print(str2)
result
1000
1000.0
The number 1e3 seems to be a string type after being converted to 1000.0.
It was also mentioned in the above book (@ No. 831/12833).
