On Monday, though, Hollande gripped Macron's arm before the two men walked side by side.
Yet the election result is far from a guarantee Macron will be as successful as many investors hope: the voter absentee rate was the biggest in nearly 50 years, indicating a lukewarm reception may be awaiting Macron's administration, from not only whatever groundswell of populism Le Pen has managed to cultivate, but also those committed to more ground-up, socialistic policies that are part of France's political climate in the modern age.
"With this massive result, the French have designated the patriotic alliance as the main force of opposition", Le Pen said in a speech which some media suggested was triumphant in tone.
Helbert's colleague, French politics expert Professor Peter McPhee, added that while there had been a rise in populist leaders across Europe in recent years, they had failed to use this momentum to take office. "More than ever in the forthcoming months France will need you", Le Pen said.
Macron's fluent English could make personal chemistry easier. He defeated the far-right candidate Marine Le Pen of the National Front by 65.7% to Le Pen's 34.3% of the votes.
Macron's presidential victory came after a bruising race marked by negative campaigning and a last-minute hacking attack targeting his campaign. In an interview with French regional newspaper La Voix du Nord, Macron said "a decision" on the Polish issue would be taken "in the three months following my election".
Addressing his supporters in the grand courtyard of the Louvre, Macron said he would defend France and Europe.
"We can't have a Europe which debates on every decimal of each country's budgetary issues but decides to do nothing when faced with one European Union member behaving like Poland or Hungary, on issues like university and knowledge, refugees, fundamental values", he said.
The last time France had "cohabitation" was under President Jacques Chirac in 1997-2002, who described the setup as a state of "paralysis".
French President-elect Emmanuel Macron laid the groundwork Monday for his transition to power, announcing a visit to Germany and a name change for his political movement and appearing with his predecessor at a solemn World War II commemoration. He conducted a courageous, pro-European campaign.
The measured forays into foreign affairs during the campaign signaled that France's youngest president is aware of his limitations and is allowing himself time to bone up before crafting his diplomacy, some experts say.
But his victory may actually symbolize an overwhelming rejection of Le Pen, more so than an overwhelming endorsement of Macron and his pro-globalization policies. She said mass immigration caused by globalization left French people feeling "dispossessed" of their country.
Modi had yesterday greeted Macron for his electoral win in a tweet. "I look very much forward to working with him!"
Trump did not endorse any candidate in the election, though many believed he supported Le Pen after comments he made in April in apparent praise of the far-right candidate's tough stance on immigration.
What he said: "The growth in threats of terrorism and militant extremism is accompanied by an escalation of local conflicts and the destabilisation of whole regions. In these conditions it is especially important to overcome mutual mistrust and unite efforts to ensure global stability and security".
This French election also generated great interest in Africa, which has many countries psychologically and economically linked to France due to a colonial history.
Ms Le Pen threatened to tear up the European Union order that has, to a greater or lesser degree, stood up to President Putin's intervention in Ukraine and seizure of Crimea.
