python - Read CSV file using Pandas: complex separator -


i have csv file want read using python panda. header , lines looks following:

           ^b^c^d^e  ^f          ^g           ^h^i^j^k^l^m^n

clearly seen that, separator ^, there odd spaces. how can read file perfectly?

i using following command read csv file:

df = pd.read_csv('input.csv', sep='^')

use regex \s*\^ means 0 or more whitespace , ^, have specify python engine here avoid warning regex support:

in [152]:  t="""a           ^b^c^d^e  ^f          ^g           ^h^i^j^k^l^m^n""" df= pd.read_csv(io.stringio(t), sep='\s*\^', engine='python') df.columns out[152]: index(['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n'], dtype='object')

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
